Tin

Tin (Sn) is a silver-white metal that has the atomic number 50 in the periodic table. It is located in Group 14 of the periodic table. It has the symbol Sn.

Tin occurs very rarely in its elemental form in nature instead in the ore cassiterite which is Tin oxide. This is usually obtained through heating with Carbon to reduce the Tin oxide compound. Tin has a number of uses primarily for coating steel in food containers or for making foil sheets. Tin has a crystalline structure and when a bar of Tin is bent a noise made like a screech is this crystal structure breaking, this is known as a tin cry. Tin has been known as an element to humans for a long time since 3000BC when it was used in the production of bronze. It was alloyed with copper to improve the properties. It is located in Group 14 as a metal. It has a melting point of 231°c and a boiling point of 2620°c.

FAQ's

What is the Melting Point for Tin?

Tin has a Melting Point of 231.97°F, meaning at 231.97°F it will turn to a liquid.

What is the Boiling Point for Tin?

Tin has a Boiling Point of 2602°F, meaning at 2602°F it will turn to a Gas.

What is the Electronegativity of Tin?

Tin's Electronegativty is 1.96. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

What is the Heat of Vaporization of Tin?

Tin has a Heat of Vaporization of 295.8 kJ/mol.

Uses

Used as a coating for steel cans since it is nontoxic and noncorrosive. Also in solder (33%Sn:67%Pb), bronze (20%Sn:80%Cu), and pewter. Stannous fluoride (SnF2), a compound of tin and fluorine is used in some toothpaste.

Sources

Principally found in the ore cassiterite(SnO2) and stannine (Cu2FeSnS4).
