Brief Summary

Tin is a Poor Metals with the symbol 'Sn' and contains 50 Protons & Electrons with 69 neutrons in the nucleus of the atom. Tin has an atomic mass of 118.71 g/mol and, at a temperature of 20°C, has a density of 7.29 g/cm³. It will melt at a temperature of 232°C and boil at 2270°C.

Tin has been known since prehistoric times and is named 'Tin' Latin word "stannum" meaning "tin".

Some common usages for Tin: coating for steel cans.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
