Question

The addition of electron shells results in _____

Answer 1

Answer:

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.
