we write the formula of zinc chloride like zncl2 and not write it formula zncl because the valency of zn is 2 while it is 1 for cl . So 2 atoms of cl will be there in the compound.

Because valency of zinc is 2 and valency of cl is 1 . So after interchanging their valencies while forming their compound it becomes zncl2 rather than zncl .Hope it helps u pls mark it as brainliest.
