Chemistry- Periodic Table- Element: Sulphur

[Guest guest]

Marie, thank you so much for this link. What amazing information on Sulphur. I just had to share the marvelous site and information.http://theodoregray.com/PeriodicTable/Elements/016/index.s7.html===========

My periodic table poster is now available!

Sulfur is the element of war. It is the biblical brimstone (as in fire

and brimstone), and it is one of the three ingredients in gunpowder.

Like lead, gold, and phosphorus it is one of the classic elements of

alchemy. Sulfur is also one of the elements with an absolutely

unmistakable smell.

The smell of sulfur makes me think of gunpowder, because that's what I

used to make with it as a teenager. Burning sulfur is unpleasant, but

sulfur powder itself I find very pleasant, though possibly this is just

because of its long association with the excitement of making fireworks

and the like. Other people may find the smell less uplifting.

In addition to its warlike uses, sulfur is used in medicine and

gardening, which means you can buy it in pharmacies and garden centers

(see below for specific examples of each). This is great if you need

some to make gunpowder.

Seeing the above description of sulfur, reader Rusty Tanton was

compelled to try to balance my warlike view of sulfur. I reproduce here

in its entirety his eloquent defense of sulfur:Apologies

if you've heard all this before, but I couldn't resist sharing some

fascinating information regarding sulfur remembered from my

college/graduate classes. I too have something of an inexplicable

fondness for sulfur. It's the biogeek in me. Sulfur is arguably one of

the most critical elements in biology after carbon. Certainly a case

can be made for other elements such as sodium, but to me it is not

merely the essential nature of sulfur that makes it so neat, but the ways

in which it is essential. Sulfur is a component of two important amino

acids, cysteine and methionine. Amino acids are, of course, the

building blocks of proteins, and it's here that the primary role of

sulfur in these molecules becomes apparent--it's critical for shaping

the three-dimensional structure of many (actually most, if memory

serves) proteins, especially in sulfur-sulfur bonds. The

three-dimensional structure of proteins is, of course, critical for

their functions, especially as enzymes and structural polymers. Imagine

Biology without, or with limited, three-dimensional proteins! The

difference between the hardness of keratin in fingernails and hair and

its softness in skin is related to how many sulfur-sulfur bonds are

present. Sulfur also provides a binding site in many enzymes for the

molecules to be catalyzed. The importance of sulfur in biology in

general and proteins in particular can be seen in most anyone's

breakfast or college prank--there's a reason egg yolks have such high

concentrations of the stuff. Sulfur also plays a critical role in

alternative biological pathways. Some bacteria use sulfur compounds as

their means of respiration in anaerobic conditions, and some

(especially of the deep-sea thermal vent variety) rely exclusively on

processing sulfur compounds in thermal vent exhaust as their source of

energy. These types of bacteria are extremely different from all other

known forms of life, and it is generally thought that they represent a

line that diverged extremely early in the history of life, before

eukaryotes arrived. Some speculate that they may in fact represent the

most primitive forms of life--that sulfur respiration and/or metabolism

came first. I suppose I've probably mis-remembered some things over the

years, but I think most of what I've been relating is accurate...

Rather than seeing sulfur as an element of fire and brimstone, I've

always seen it as an element of life, odors and all. Well,

it sounds mostly correct to me as well, and I really love that someone

took the time to defend their favorite element. Me, I still think of it

as fire and brimstone, especially after completing my sulfur inlay

project (see below).

Flowers of sulfur.This

sulfur was purchased at a Walgreens pharmacy in April 2002. They had

only one partially used bottle left, which no one knew the use of!

Many years ago I used to buy sulfur and saltpeter from pharmacies to

grind up into gunpowder (the carbon came from readily available

charcoal). I had to be sure not to buy both sulfur and saltpeter from

the same pharmacist. Back then neither seemed to raise any eyebrows,

and I don't think I ever had to use my planned excuse that "my mom

asked me to buy this for her, I don't know what she's going to do with

it".

But in 2002, it seems people don't buy sulfur at the pharmacy anymore.

I actually had half seriously planned to say "my wife asked me to buy

this for her, I don't know what she's going to do with it", but when

the stern-faced pharmacist asked me, staring over his glasses, what I

planned to do with it, I broke down and told him the truth. It worked.

Powdered sulfur from old chemistry set.

This bottle is from a 1950's chemistry set I got on eBay after consulting this trusty reference book about radioactive collectables.

It's an "ATOMIC ENERGY" set (that kind of thing was big in the '50s),

but it also includes an assortment of standard-issue chemistry set

chemicals.

According to the book's table of going rates for these things, I got a

good deal on the chemistry set, though it is not in perfect condition

and is missing some components. Modern chemistry sets are pretty wimpy,

but I have to say that, aside from the uranium ore and the radium, this

set is pretty tame as well. It even proudly claims to contain "no

dangerous or explosive chemicals". I mean really, where's the fun in

that? Here's a picture of the set:

Sample from the RGB Set.

The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.

To learn more about the set you can visit my page about element collecting for a general description or the company's website

which includes many photographs and pricing details. I have two

photographs of each sample from the set: One taken by me and one from

the company. You can see photographs of all the samples displayed in a

periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.

The picture on the left was taken by me. Here is the company's version

(there is some variation between sets, so the pictures sometimes show

different variations of the samples):

Sample from the Everest Set.

Up until the early 1990's a company in Russia sold a periodic table

collection with element samples. At some point their American

distributor sold off the remaining stock to a man who is now selling

them on eBay. The samples (except gases) weigh about 0.25 grams each,

and the whole set comes in a very nice wooden box with a printed

periodic table in the lid.

This can was sold for medicinal purposes probably 40-50 years ago from

the look of it. The seller described it as an eight-pound can with

about two pounds used, leaving six pounds in it. It definitely smells

you want to buy six pounds of antique sulfur.

Soil Sulfur.

It turns out all my adventures in buying sulfur at pharmacies were

quite unnecessary: You can buy it by the pound with no questions or

funny looks at any garden supply store. It's used as a soil acidifier

and pesticide, and can be had as crystals or powder (see next sample

for powder form). Of course the purity is not nearly as high as

pharmacy sulfur (my bag came with a "guaranteed analysis" of >90%

sulfur). But that's good enough for me.

Cast fish.

This is a fish cast out of sulfur in a cornbread mold. Cast sulfur?

If you divide the periodic table up into broad groups, the first thing

you notice is that almost everything is a metal. The transition metals

alone are the largest group, but alkali metals, alkali earth metals and

rare earth metals are all metals too. And then of course there are the

normal metals to the right of the transition metals. The metalloids

(silicon, germanium, arsenic, antimony, tellurium, polonium) are a lot

like metals, and almost everything that's left are gases. In fact, the

only elements that are not gases, and not metals or metalloids, are

carbon, phosphorus, sulfur, selenium, bromine, and iodine. (And bromine

and iodine are just barely not gases.)

But despite not being a metal, and despite the fact that you almost

always see it in the form of a powder, sulfur can easily be melted and

cast on an electric stove. I wouldn't do it on a gas stove because of

the danger of it catching fire, and even on an electric stove melting

sulfur is a nasty proposition. Sulfur is rather smelly stuff, and it

forms choking sulfur dioxide fumes: If you have any sort of breathing

difficulty (and even if you don't) a whiff of the fumes from molten

sulfur can choke you up pretty bad.

One neat thing about molten sulfur is that it looks much hotter than it

really is. A just-cast ingot of sulfur, which is only at a couple

hundred degrees Fahrenheit (nowhere nears glowing temperature) looks

exactly like red-hot cast iron, because the natural color of molten

sulfur is a dull glowing-red. As it cools, it looks hotter and hotter

as the sulfur turns from red to orange to yellow.

A surprising thing happens to cast sulfur after it's finished cooling:

Up to an hour later it changes crystal structure from deep yellow,

sharply-defined dendritic crystals to the more familiar pale yellow

powdery, flaky crystals. I don't know what exactly is happening, but in

the case of this fish, it happened one scale at a time over the course

of about

an hour, until finally the whole fish had turned pale.

I made this fish from cheap 90% pure soil sulfur from a garden shop.

Coal scrubber residue.

This sulfur is waste from the desulfurization of coal. From the eBay listing:Sulfur

from a desulfurization unit at a southwestern Pennsylvania coke plant.

Specimen is approximately 7.9 x 2.2 x 1.0 cm. Sulfur is recovered from

coke oven gas by reacting hydrogen sulfide with sulfur dioxide. Nearly

pure elemental sulfur results from this environmentally friendly

process. Sulfur stalactites and stalagmites form around leaking valves.As industrial waste goes, this stuff is quite pretty.

Assorted glow-in-the-dark paints.

This lovely array of glow-in-the-dark (phosphorescent) powders

illustrates the range of colors and the brightness of modern luminous

paints. Green and aqua are europium doped strontium aluminate, the

brightest of all the modern phosphorescent powders. Blue is a alkali

earth silicate, while red and orange are older, noticeably less bright

zinc sulfides. (The difference in brightness is so great it was

difficult to get a photograph that showed the glowing of the zinc

sulfide without overexposing the other colors!) The powder packets are

meant to be mixed with paint, nail polish, or whatever, rendering them

luminous. The bottle in the back is ready-made paint, while the small

tub is a heat-and-dip powder.

This set was kindly donated by Ready Set Glo: Visit their website at www.readysetglo.com or their eBay store.

(The "purity" listed below doesn't mean a whole lot since this is a

mixture of several different compounds: I'm just indicating that this

sample is not a simple element but rather a mixed compound.)

Pyritized Ammonite.

A fossil is the impression left when the body of an ancient animal or

plant is encased in some kind of mud or sand, which turns into rock

over great expanses of time. After the matrix around the object has

become firm enough to hold its shape, the object itself is slowly

replaced by some other mineral that works its way in from the

surrounding matrix. If all goes well, the rock or mineral formed where

the body used to be is different enough from the surrounding rock or

mineral that it's possible to separate them and rediscover the original

shape of the object. (If it doesn't go well, either there's no fossil

formed, or it's one that is so subtle you just don't notice it.)

A fossil can be formed out of all kinds of different minerals, so there

are really two entirely separate ways to describe one: What it's a

remnant of, and what it's made out of. This sample is a fossil of a

type of animal called an Ammonite, but even more interestingly, it

happens to be made of pyrite (iron sulfide), also known as "fool's

gold" because it looks a lot like gold.

Imagine that: An animal shape recreated in shiny gold crystals, and it's an entirely natural process. Amazing.

Technical details: This is a Pleurocerus Ammonite from the Jurassic age, found in Nuremburg, Germany.

Photo Card Deck of the Elements.

In late 2006 I published a photo periodic table and it's been selling well enough to encourage me to make new products. This one is a particularly neat one: A complete card deck of the elements

with one big five-inch (12.7cm) square card for every element. If you

like this site and all the pictures on it, you'll love this card deck.

And of course if you're wondering what pays for all the pictures and

the internet bandwidth to let you look at them, the answer is people

buying my posters and cards decks. Hint hint.

[Guest guest]

Willow my friend you are very welcome, now I need your help and others. Please

help save the Mountains of the Appalachians, my home and soul. Please pass this

on and help the fight or they will be gone for ever. We can take the fossil fuel

without taking the mountain, or just find a different direction wind, textile

hemp, there are other ways. The coal has been taken from the mountains for

decades but the mountains remain now they take the mountain blasting and need

LESS HUMAN employees so it is more profitable. PLEASE HELP!

> Sulfur is the element of war. It is the biblical brimstone (as in fire

> and brimstone), and it is one of the three ingredients in gunpowder.

> Like lead, gold, and phosphorus it is one of the classic elements of

> alchemy. Sulfur is also one of the elements with an absolutely

> unmistakable smell.

>

> The smell of sulfur makes me think of gunpowder, because that's what I

> used to make with it as a teenager. Burning sulfur is unpleasant, but

> sulfur powder itself I find very pleasant, though possibly this is just

> because of its long association with the excitement of making fireworks

> and the like. Other people may find the smell less uplifting.

>

> In addition to its warlike uses, sulfur is used in medicine and

> gardening, which means you can buy it in pharmacies and garden centers

> (see below for specific examples of each). This is great if you need

> some to make gunpowder.

>

> Seeing the above description of sulfur, reader Rusty Tanton was

> compelled to try to balance my warlike view of sulfur. I reproduce here

> in its entirety his eloquent defense of sulfur:

> Apologies

> >if you've heard all this before, but I couldn't resist sharing some

> >fascinating information regarding sulfur remembered from my

> >college/graduate classes. I too have something of an inexplicable

> >fondness for sulfur. It's the biogeek in me. Sulfur is arguably one of

> >the most critical elements in biology after carbon. Certainly a case

> >can be made for other elements such as sodium, but to me it is not

> >merely the essential nature of sulfur that makes it so neat, but the ways >in

which it is essential. Sulfur is a component of two important amino

> >acids, cysteine and methionine. Amino acids are, of course, the

> >building blocks of proteins, and it's here that the primary role of

> >sulfur in these molecules becomes apparent--it's critical for shaping

> >the three-dimensional structure of many (actually most, if memory

> >serves) proteins, especially in sulfur-sulfur bonds. The

> >three-dimensional structure of proteins is, of course, critical for

> >their functions, especially as enzymes and structural polymers. Imagine

> >Biology without, or with limited, three-dimensional proteins! The

> >difference between the hardness of keratin in fingernails and hair and

> >its softness in skin is related to how many sulfur-sulfur bonds are

> >present. Sulfur also provides a binding site in many enzymes for the

> >molecules to be catalyzed. The importance of sulfur in biology in

> >general and proteins in particular can be seen in most anyone's

> >breakfast or college prank--there's a reason egg yolks have such high

> >concentrations of the stuff. Sulfur also plays a critical role in

> >alternative biological pathways. Some bacteria use sulfur compounds as

> >their means of respiration in anaerobic conditions, and some

> >(especially of the deep-sea thermal vent variety) rely exclusively on

> >processing sulfur compounds in thermal vent exhaust as their source of

> >energy. These types of bacteria are extremely different from all other

> >known forms of life, and it is generally thought that they represent a

> >line that diverged extremely early in the history of life, before

> >eukaryotes arrived. Some speculate that they may in fact represent the

> >most primitive forms of life--that sulfur respiration and/or metabolism

> >came first. I suppose I've probably mis-remembered some things over the

> >years, but I think most of what I've been relating is accurate...

> >Rather than seeing sulfur as an element of fire and brimstone, I've

> >always seen it as an element of life, odors and all. Well,

> If you divide the periodic table up into broad groups, the first thing

> you notice is that almost everything is a metal. The transition metals

> alone are the largest group, but alkali metals, alkali earth metals and

> rare earth metals are all metals too. And then of course there are the

> only elements that are not gases, and not metals or metalloids, are

> carbon, phosphorus, sulfur, selenium, bromine, and iodine. (And bromine

> and iodine are just barely not gases.)

> But despite not being a metal, and despite the fact that you almost

> cast on an electric stove. I wouldn't do it on a gas stove because of

> the danger of it catching fire, and even on an electric stove melting

> sulfur is a nasty proposition. Sulfur is rather smelly stuff, and it

> forms choking sulfur dioxide fumes: If you have any sort of breathing

> difficulty (and even if you don't) a whiff of the fumes from molten

> sulfur can choke you up pretty bad.

>

> One neat thing about molten sulfur is that it looks much hotter than it

> really is. A just-cast ingot of sulfur, which is only at a couple

> hundred degrees Fahrenheit (nowhere nears glowing temperature) looks

> exactly like red-hot cast iron, because the natural color of molten

> sulfur is a dull glowing-red. As it cools, it looks hotter and hotter

> as the sulfur turns from red to orange to yellow.

>

> A surprising thing happens to cast sulfur after it's finished cooling:

> Up to an hour later it changes crystal structure from deep yellow,

> sharply-defined dendritic crystals to the more familiar pale yellow

> powdery, flaky crystals. I don't know what exactly is happening, but in

> the case of this fish, it happened one scale at a time over the course

> A fossil is the impression left when the body of an ancient animal or

> over great expanses of time. After the matrix around the object has

> become firm enough to hold its shape, the object itself is slowly
