what is shielding effect
Answers
Answer:
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 in material sciences.

Answer:
A difference in the attraction forces on the electrons in the atom causes the shielding effect, which is defined as a reduction in the effective nuclear charge on the electron cloud.
Explanation:
When the number of inner electrons is large enough, they shelter the outermost electron from the nucleus, allowing it to be free of nuclear pull. This is called the shielding or screening effect.
The electrons in the valence shell are attracted to the nucleus in a multielectron atom, but they are repelled by the electrons in the inner shells. As a result of the repulsive forces acting in opposite directions, the actual force of attraction between the nucleus and the valence electrons is slightly reduced. The presence of electrons in the inner shells reduces the force of attraction imposed by the nucleus on the valence electrons, which is known as the screening effect or shielding effect.
