Question

What is the valency of nitride?

Answer 1

Valency:

• It is the combining capacity of an atom. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element.

Nitride:

• A nitride is a nitrogen based compound with a formal oxidation state of -3. Nitrides are a diverse group of compounds with several characteristics and applications.

Examples:

• Ionic nitrides are Lithium nitride $\left({\mathrm{Li}}_3\mathrm{N}\right)$ and all the alkaline earth metals can form nitrides with the general formula ${\mathrm{M}}_3{\mathrm{N}}_2$, where M is the alkaline earth metal.

Valency of Nitride:

• The valency of nitride is the same as its formal charge. Hence, valency of nitride is 3.
