WebJ.C. Slater proposed an empirical constant that represents the cumulative extent to which theother electrons of an atom shield (or screen) any particular electron from the nuclear charge. Thus, Slater's screening constant σ is used as Z ∗ = Z − σ Here, Z is the atomic number of the atom and hence is equal to the actual number of protons ...

WebThe 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. As a result, atoms will be larger.
