Decreases down the group

Vedclass · Answer

(B) As we move down Group $1$ (alkali metals),the atomic size increases due to the addition of new shells. Due to the increase in atomic size,the valence electron becomes farther from the nucleus,and the effective nuclear charge experienced by the valence electron decreases. Consequently,the force of attraction between the nucleus and the valence electron decreases,making it easier to remove the electron. Therefore,the ionization energy decreases down the group.

How does the ionization energy of the elements of Group $1$ change as we move down the group?
