Nitride

The nitride ion is N^{3−^{(a nitrogen atom plus three electrons).}}

A nitride (compound) is a compound that has nitrogen with more electropositive elements.

Some nitrides are salt-like compounds, but many are inert compounds similar to carbides.

Nitride has 7 protons (like nitrogen) but has 10 electrons, 3 more than nitrogen. The mass still matches Nitrogen's with a mass of 14 amu.

Examples

lithium nitride (Li₃N)
boron nitride (BN)
titanium nitride (TiN) - often used as a coating on metals to provide resistance to wear
