We know that the valency of Chlorine is 1.
If M is forming a chloride in MCL2, the valency of M should be 2.
IT is given that MCL2 is a solid with high melting point which establishes that MCL2 is an ionic compound.
Thus we infer that M is a metal and it belongs to the group 2 of the periodic table.
