I believe you mean silicon nitride. Please see the link.
If you think to silicon nitride, Si3N4, this is a chemical compound with covalent bonds.
K3N is not an element. It is a compound known as potassium nitride.
The formula for copper(I) nitride is Cu3N. Nitride has a valency of -3
This is the chemical formula of calcium nitride.
Magnesium(I) Nitride is the name of Mg3N.
Sodium Nitride is Na3N
Lithium Nitride
126 protons are in nitride.
The formula is CrN. It is called Chromium nitride and Chromium(III) nitride. Chromium also forms second interstitial nitride, dichromium nitride - Cr2N
The chemical formula for a nitride ion is N-3.
The formula for potassium nitride is K3N. It consists of three potassium ions (K+) and one nitride ion (N3-).
Nitride typically has a charge of -3, as it is made up of the nitride ion (N3-). This means that nitride has gained three electrons to achieve a stable electronic configuration.
