Brief Summary

Neodymium is a Lanthanide with the symbol 'Nd' and contains 60 Protons & Electrons with 84 neutrons in the nucleus of the atom. Neodymium has an atomic mass of 144.242 g/mol and, at a temperature of 20°C, has a density of 7 g/cm³. It will melt at a temperature of 1010°C and boil at 3127°C.

Neodymium was discovered by von Welsbach in 1895 and is named 'Neodymium' Greek words "neos" meaning "new" and "didymos" meaning "twin".

Some common usages for Neodymium: coloring glasses and ceramics; filtering infrared radiation.

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.
