Toxicity
Having a lot of tin in a person’s system can cause problems such as acute effects including things like stomachaches and headaches. But the long-term effects include depression, liver damage, malfunctioning of immune systems, or brain damage.
used as a coating for other metals to prevent corrosion
found in some toothpaste (SnF5)

Manufacturing and or Production
Tin is found naturally, in the earth’s crust. It also can be found in “cassiterite(SnO2) and stannine (Cu2FeSnS4) in Malaya and Indonesia, Zaire and Nigeria, Bolivia and Thailand. Primary mining areas are Malaysia, Sumatra, Russia, China, Bolivia, and Zaire.”

History/Discovery
People have been using tin since ancient times, so we don’t know one single person who discovered the element.

Interesting Aspects of Tin
Tin can be used for Coating for steel cans
Tin ceilings, signs, tiles, tin soldiers, whistles, containers and tin roofs.

The Internet Resources

Background things to know

Chemsoc-Tin - This website has a picture of tin and it gives you a description of tin. It also gives you the origin of the word and it comes from the “Latin word ‘stannum’ which relates to the word ‘stagnum’ which means dripping because tin melts easily.
Tin- Tamuk.edu - This website has all the basics, but it doesn’t tell you too much. It tells you about how was known back in ancient time. It also tells you about where you can find it in the world, which is a good thing to know. For example, you can find it places like Malaya and Indonesia.

Good Information

Chemicool- Tin - This website is useful because it tells you everything you need to know about Tin. For example, it tells you the density, boiling point, and what group it is in. This website also tells you about the states, energies, the oxidation and electrons, appearances and characteristics, reactions, other forms that it takes up, radius, conductivity and abundance.
Environmental Chemistry- Tin - Environmental Chemistry.com is useful because it tells you just about everything you need to know, for example, it tells you about the health part of tin, that you never really see. This website also tells you about the chemical compounds of tin.
Tin- Wikipedia - On this website, it tells you the basics, but it doesn’t really tell you much more. It does tell you what the crystal structure is and what its heat of fusion is, which I haven’t seen on other websites. It also tells you what it can be used for and a brief history about it. Not too useful, but something good to refer back to.

Great Information

American Elements- Tin - Americanelements.com is very useful because it tells you about the solutions that it includes. On the side of the webpage, it has about 75 links about tin and what kind of compounds it makes. It also gives you the isotopes and the atomic mass and its abundance on earth.
Minerals-Tin - Minerals.usgs.gov tells you the basics but tells you mainly about the history of it. It tells you about where most tin comes from and how ancient people used it. Tin is relatively scarce “with an abundance in the earth’s crust.” Most of the world’s tin is produced from placer deposits.
Periodic lanl- Tin - Periodic.lanl.gov is interesting because it tells you that tin’s primary source is cassiterite (SnO2). Also, since tin is made up of crystals, when it is bent, a tiny “tin cry” is heard. It “cries” because these crystals break. Ordinary tin is soft / bendable. This website also tells you about the other forms that tin comes in and the alloys. Tin resists distilled sea water and soft tap water.
Radiochemistry- Tin - Radiochemistry.org is very useful because it tells you about the cost of tin, how one should handle tin, the forms, properties, the sources and history of it. This is useful because it tells you all the information that you need to know without telling you too much and it helps you find what you need to know easily.
Tin- Chemical Elements - This website tells you the atomic structure and its color, density, and melting point. It also tells you all the basic information. Along with that, it tells you about Isotopes and Half Lives. This website also tells you about the Energy levels, for example, it has five different energy levels ranging from 2 to 18.
Tin-Chemistry About - Chemistry.about.com tells you about the properties and the 2270◦C boiling point. “It possesses a highly crystalline structure and is moderately ductile.” It also tells you that tin has a tetragonal structure. It tells you that tin can be used to coat other metals to prevent corrosion. Chemistry.about.com also tells you the ionic radius, which is 71 (+4e) 93 (+2) and many more things about the property of tin.
Web Elements- Tin - This website is useful in many ways. For example, it tells you the essentials, the description, and shows you what it looks like. This website also hells you what it resists and what it combines with. Along the sides of this website, there are links that can connect you to the properties, the compounds, and where you can find tin around you.

Very Useful

Minerals Information Institute- Tin - Mii.org has the basics but it also has substitutes and alternative sources of tin, which I haven’t seen on other websites. For example, you can use tin as a non-toxic substitute for lead in soldiers, pewter, and shotgun pellets. It tells us about the history of the word and where you can find the element. This website also tells you about what tin is used for.
Tin- Education Jlab - This website is really useful because it tells you not only the basics and other chemical properties, but it tells you the history. Tin has been used for about 5500 years. This website also tells you where it can be most likely found. It tells you about the properties concerning corrosion and what tin actually is.
Tin: Accu-cell - Acu-call.com talks about the basics, like the other websites, but it also talks about the health effects of tin. Tin is mainly used in organic substances. Tin can cause acute effects including things like stomachaches and headaches. But the long-term effects include depression, liver damage, malfunctioning of immune systems, or brain damage. Tin is soft and pliable and is not easily oxidized. It resists corrosion because it has a protective oxide film. This website also tells you about the effects tin has on the environment.
