​

Answer 1

Answer:

This decrease in the force of attraction exerted by the nucleus on the valence electrons due to the presence of electrons in the inner shells is called screening effect or shielding effect.

Answer 2

Screening effect

The screening effect is otherwise called the shielding impact. The peculiarity happens when the core diminishes its power of fascination on the valence electrons because of the presence of electrons in the internal shell. This is known as a screening impact. External electrons experience fascination from the core and shock from the internal electrons. As the fascination between the core diminishes, the aversion increments between the internal electrons and external electrons.
