Question

Write the symbol and valency of nitride.

Answer 1

• Nitride is a nitrogen compound that never encounters a protic solution (In chemistry a protic solvent is a solvent that has a hydrogen atom bound to oxygen as in a hydroxyl group or nitrogen as in an amine group).
• The oxidation state of the nitrogen is −3.
• It has an average ionic radius of 140 pm.
• Hence, the symbol of nitride is ${\mathrm{N}}^{3-}$ and valency is -3.
