Question

What is screening effect? How is it related to IE?​

Answer 1

Explanation:

Screening effect- It is described as a decrease in shielding effort between the nucleus and last orbital due to electrons present between them i.e., greater thescreening effect, easier the removal of electron.

Answer 2

Answer:

Explanation:

Screening effect is also known as the shielding effect. The phenomenon which occurs when the nucleus reduces its force of attraction on the valence electrons due to the presence of electrons in the inner-shell. This is known as a screening effect.

The electrons present in the inner shells act as screens between the nucleus and the valence shell electrons. As inner electron-shells increase, the IP decreases.
