प्रश्न
Give reason for the following:
Ionisation potential decreases down a group.

उत्तर
As we move down a group, the atomic size increases due to an increase in the outermost shells. As a result, moving down a group is easier to remove because we don't need as much energy. As a result, the ionisation potential of a group falls.
