WebThe shielding effect describes the balance between the pull of the protons on valence electrons and the repulsion forces from inner electrons. The shielding effect explains … WebApr 4, 2024 · 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.

WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2. iowa high school wrestling live
