What is Shielding Effect and Screening Effect

Answer: 

• Shielding Effect:

The shielding effect, also known as atomic shielding or electron shielding, is the attraction between an electron and the nucleus in any atom with more than one electron. The shielding effect is 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’s a type of electric-field screening that’s a little different. The shielding effect, also known as atomic shielding or electron shielding, describes the attraction between an electron and the nucleus in any atom having more than one electron. 

• Screening Effect:

The shielding effect is just another name for the screening effect. Given the existence of electrons in the inner shell, the nucleus’ force of attraction on the valence electrons is lowered. The screening effect is the terminology for the above phenomena. 

Inner electrons repel outer electrons, which are attracted to the nucleus. As the attraction between the nucleus lessens, the repulsion between the inner and outer electrons develops.
