What is the chemical formula for the ionic compound formed when elements of Ca and N react?
Calcium nitride is a red-brown, crystalline solid made up of calcium and nitrogen. Its chemical formula is
(3 x Ca2+) = +6
(2x N3-) = -6
The net charge of the compound will be zero.
- Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements:
- 3 Ca + N2 → Ca3N2
Crystal structure - Cubic, cI80
