Based on lattice energy and other considerations which one of the following alkali metal chlorides is expected to have the highest melting point?
As we learnt in
Alkali Metal -
Each period starts with an alkali metal whose outermost electronic configuration is ns1
-
Despite the fact that has higher lattice energy than , has lower melting point because of its covalent nature. Also, as we go down the group's lattice energy generally decreases as size of alkali metal atom increases.
