Question

8) When an anion forms, the valence energy level has additional electrons placed into it and these additional
electrons exert a shielding influence (remember that electrons repel each other). What do you expect to be the
effect of this on the atomic radius?

Answer 1

the atomic radius get bigger.

this is because as you add more electrons to an anion the electrons get farther apart.

they do this because they don't like each other so when you add more they need more space to stay away from each other
