Brief Summary

Tungsten is a Transition Metal with the symbol 'W' and contains 74 Protons & Electrons with 110 neutrons in the nucleus of the atom. Tungsten has an atomic mass of 183.84 g/mol and, at a temperature of 20°C, has a density of 19.26 g/cm³. It will melt at a temperature of 3407°C and boil at 5927°C.

Tungsten was discovered by Elhuyar in 1783 and is named 'Tungsten' Swedish words "tung" and "sten" meaning "heavy stone".

Some common usages for Tungsten: used widely in electronics industry.

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.
