Brief Summary

Nickel is a Transition Metal with the symbol 'Ni' and contains 28 Protons & Electrons with 31 neutrons in the nucleus of the atom. Nickel has an atomic mass of 58.6934 g/mol and, at a temperature of 20°C, has a density of 8.91 g/cm³. It will melt at a temperature of 1453°C and boil at 2732°C.

Nickel was discovered by Cronstedt in 1751 and is named 'Nickel' German word "kupfernickel" meaning "false copper".

Some common usages for Nickel: electroplating metal alloys and nickel-cadmium batteries.

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.
