Brief Summary

Silicon is a Metalloid with the symbol 'Si' and contains 14 Protons & Electrons with 14 neutrons in the nucleus of the atom. Silicon has an atomic mass of 28.0855 g/mol and, at a temperature of 20°C, has a density of 2.33 g/cm³. It will melt at a temperature of 1410°C and boil at 2355°C.

Silicon was discovered by Berzelius in 1824 and is named 'Silicon' Latin word "silex" meaning "flint".

Some common usages for Silicon: in glass and semiconductors.

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.
