In chemistry, the shielding effect sometimes referred to as atomic shielding or electron shielding describes the attraction between an electron and the nucleus in any atom with more than one electron. The shielding effect can be defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces on the electrons in the atom. It is a special case of electric-field screening. This effect also has some significance in many projects i… WebElectron shielding refers to the blocking of valence shell electron attraction by the nucleus due to the presence of inner-shell electrons. Electrons in an s orbital can shield p electrons at the same energy level because of the spherical shape of the s orbital. Electrons in paired spin configurations are slightly easier to remove than unpaired ...
