Question

Arrange lithium, rubidium, potassium, sodium ionization energy in ascending order

​

Answer 1

Answer:

the correct order of ionization energy is Cs < Rb < K < Na < Li(option A)

Answer 2

Answer:

As the atomic radius increases then the removal of electrons will be easy. Hence, Li,Na, K, Rb, Cs are Group IA elements from Li to Rb the ionization energy decreases. Thus, the correct order of ionization energy is Cs < Rb < K < Na < Li.
