Question

What affects atomic radius?

Answer 1

Answer:

Explanation:

A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.

Answer 2

Answer:

In the periodic table, the atomic radius of element tends to decrease as you move across a row from left to number of protons increase left to right, leading to a greater attractive force in the nucleus the stronger attraction pulls the electrons closer in reducing the radius.
