Screening Effect
The screening effect, also known as shielding effect or electron shielding, refers to the reduction in the effective nuclear charge experienced by an electron in an atom due to the presence of other electrons. This effect is a result of the electron-electron repulsions that occur in multi-electron atoms, which weaken the attraction between the positively…
