Question

what is shielding effect?​

Answer 1

Answer:

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.

Answer 2

Answer:

Shielding Effect:-

In a multielectron atom, the electrons of the valence shell are attracted to the nucleus and also these electrons are repelled by the electrons present in the inner shells. On account of this, the actual force of attraction between the nucleus and the valence electrons is somewhat decreased by the repulsive forces acting in opposite directions.
