Question

In a sentence, describe the relationship between atomic number and the amount of ionization energy as you go down a group on the periodic table.

Answer 1

Explanation:Within a group, the ionization energy decreases as the size of the atom gets larger. ... In this situation, the first electron removed is farther from the nucleus as the atomic number (number of protons) increases. Being farther away from the positive attraction makes it easier for that electron to be pulled off.
