Silver nitride is formed when a silver cation that has a 1+ charge combines with a nitrogen anion that has a 3- charge. write the formula for the compound silver nitride.

Silver's chemical symbol is Ag, and it has a 1+ charge. Nitrogen's chemical symbol is N, and it has a 3- charge. For silver and nitrogen to form a compound, their charges must cancel out to zero. Therefore, we would need 3 silver atoms for each nitrogen atom to balance the charges out. The formula for the silver nitride compound would be Ag3N.

Ibelieve its a because an empirical formula usually has a ch in it your options are a or b
