Question

In an atom how it is possible that force by nucleus on valence electron decreases due to inner electrons (shielding effect).

Answer 1

Answer:

The shielding effect explains why valence shell electrons are more easily removed from the atom. The nucleus can pull the valence shell in tighter when the attraction is strong and less tight when the attraction is weakened. The more shielding that occurs, the further the valence shell can spread out
