Description : Why is the ionization energy of IA class elements lowest at any stage ?
Last Answer : Any phase of the Periodic Table starts with Group- IA on the left . At any stage, from left to right, the value of ionization potential gradually increases due to atomic size contraction. For this reason, the ionization energy of the elements of the leftmost IA group is the lowest.
