shielding of electrons

Explanation:

The addition of electrons shells results in the shielding of electrons away from the nucleus, most importantly the nuclear pull resulting from the charge.

The nucleus pulls electrons to itself due to the net positive charge on it. As more electronic shell is added, the effect of the pull weakens outward. The inner shell experiences the nuclear pull more than the outer shell electrons.

The effect is responsible for a wide range of properties of elements.
