Question

Li,Na,K,Rb,Cs decreasing order of lonization potential
​

Answer 1

Explanation:

1 As one moves down a given group in the periodic table, the ionization energy decreases. In group I, for example, the ionization energies decrease in the order Li > Na > K > Rb > Cs. The reason for this is a steady increase in size of the valence electron cloud as the principal quantum number n increases
