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. WebShielding Effect on Atomic Radius. The shielding effect plays an important role in determining atomic radius. The tighter the "grip" the nucleus has on its electrons, the … WebMay 10, 2024 · The effects of adding neutrons to an atom. So neutrons are neutral in terms of charge, and adding neutrons to an atom affects its atomic mass. But when neutrons are added to the nucleus, the nuclear radius would be affected. Couldn't that affect how the charge of the nucleus is distributed within the nucleus? react find item in array
