Answer
The bond formed between metal (M) and non-metal (chlorine) is ionic bond.
As M bonds with two chlorine atoms having electronic configuration [2,8,7], so we can say that M donates two electrons to two chlorine atoms to complete their octet and therefore, it has a valency of 2.
When metal M having +2 valency combines with sulphur [2, 8, 6] having -2 valency, the formula of the compound formed is MS
When metal M having +2 valency combines with oxygen [2, 6] having -2 valency, the formula of the compound formed is MO
When metal M having +2 valency combines with nitrogen [2, 5] having -3 valency, the formula of the compound formed is M3N2.
