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?

WebApr 4, 2024 · Screening or Shielding Effect: This effect is observed in an atom having more electrons and particularly more electron shells. The electrons in the valence shell are attracted by the positively charged nucleus. While there is repulsion between the valence electrons and the electrons present in the inner shells. WebWhy does atomic radius increase down a group? there are more electrons that need more energy levels. They have a weaker force --> less full on outer e- electrons aren't as pulled together, more space effective nuclear charge (Zeff) effect that the nucleus has on outer e- Zeff: protons-inner core
