State whether the ionization potential increases or decreases on going down a group.

Solution

Ionisation potential is the energy required to remove an electron from an isolated gaseous atom. It decreases down the group because it is easier to remove an electron from a large-sized atom that has least effective nuclear charge on valence electrons.
