The formula of a metal oxide Is MO. Then write the formula of its chloride.

Text Solution

Verified by Experts

1) The valency of oxide is 2 i.e., `O^-2`
2) The formula of a metal oxide is given as MO.
3) Hence the valency of the given metal must be 2 i.e `M^(+2)`?
4) Valency of chloride is 1 i.e, Cl
5)Therefore according to criss - cross method the formula of given metal chloride will be `MCl_2`.
