Answer

Brief Explanations:

Ionization energy is the energy required to remove an electron from an atom. As we move from top to bottom in a group, the number of electron - shells increases. This causes the outermost electrons to be farther from the nucleus. The attraction between the nucleus and the outermost electrons weakens, making it easier to remove an electron and thus decreasing the ionization energy.

Answer:

Electrons get farther from the nucleus.
