Question

On what factors does ionization energy of an element depends? What happens to ionization energy as
we go down in a group?​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

Within a group, the ionization energy decreases as the size of the atom gets larger. On the graph, we see that the ionization energy increases as we go up the group to smaller atoms. In this situation, the first electron removed is farther from the nucleus as the atomic number (number of protons) increases.

Answer 2

Answer:

Within a group, the ionization energy decreases as the size of the atom gets larger. On the graph, we see that the ionization energy increases as we go up the group to smaller atoms. In this situation, the first electron removed is farther from the nucleus as the atomic number (number of protons) increases.
