Question

The softness of group 1 elements increases down the group with increasing atomic number. Give reason.

Solution

The extent of metallic bonding decreases with the increase in atomic size down the group. In other words, close-packing of atoms in crystal lattice decreases from Li to Cs, thereby resulting in an increased softness.
