Question

How is atomic size affected in groups​

Answer 1

Answer:

periodic table trends. 1) As you move down a group, atomic radius increases. WHY? - The number of energy levels increases as you move down a group as the number of electrons increases. ... Therefore, the atomic radius increases as the group and energy levels increase.

Answer 2

Answer:

In general, atomic radius decreases across a period and increases down a group. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
