Question

The magnitude of screening effect depends upon the number of

• A. Inner electrons
• B. Outer electrons
• C. Bond order
• D. Both (a) and (b)

Answer 1

The correct option is A Inner electrons

Screening effect is a phenomenon when there is reduction in nuclear force of attraction on the valence electrons due to the presence of electrons in the inner shell.
The magnitude of screening effect depends upon the number of inner electrons i.e., higher the number of inner electrons, greater will be the value of screening effect.
