valency of aluminium= 3
valency of nitrogen= 3
nitride means there is no other element present in the compound.
thus formula of aluminium nitride = AlN. using cross method. cross multiply the valencies together. That is it will become Al3N3, which can be cut down to simplest ratio of AlN.
there total no. of atoms in compound is 2.
thus percentage = 50%.
