Answer:

Al3+ < Mg2+ < Li+ < K+In these Al3+ and Mg2+ are isoelectronic species so in these size decreases with rising atomic number because on rising atomic number Zeff decreasesSize ∝ 1/Zeff where. Zff = effective nuclear charge In Li+ and K+ K+ is higher than Li+ because on moving from top to bottom in group. size decreases.
