WebApr 5, 2024 · The shielding effect explains why electrons in the valence shell are more easily removed from the atom. When the attraction is strong, the nucleus can pull the valence shell in tighter, and less tight when the attraction is weak. The greater the shielding, the further the valence shell can spread. As a result, atoms will grow in size. Important ...
