Answer

Brief Explanations:

Ionization energy decreases down a group in the periodic table. Lithium (Li), sodium (Na), potassium (K), and rubidium (Rb) are in Group 1. As we move down the group, the out - ermost electron is further from the nucleus and easier to remove, so ionization energy decreases.

Answer:

Li > Na > K > Rb
