Shielding Effect: Definition, Atomic, Formula StudySmarter

The electrons around a nucleus will circulate in a magnetic field and create a secondary induced magnetic field. This field opposes the applied field as stipulated by Lenz's law and atoms with higher induced fields (i.e., higher electron density) are therefore called shielded, relative to those with lower electron density. Electron-donating alkyl groups, for example, lead to increased shielding whereas electron-withdrawing substituents such as nitro groups lead to deshielding of th… WebDec 16, 2024 · So, the shielding effect is responsible for reducing the effective nuclear charge on the valence shell.

De-shielding effect

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… WebExplanation. The shielding effect refers to the reduced attraction between outer shell electrons (which are negatively charged) and the positively charged nucleus of an atom.
