The screening effect of inner electrons of the nucleus causes

Option: 1

A decrease in the ionisation potential

Option: 2

An increase in the ionisation potential

Option: 3

No effect on the ionisation potential

Option: 4

An increase in the attraction of the nucleus to the electrons

Answers (1)


As we have learnt,

The inner electrons create a shield between the valence electrons and the nucleus. As a result, the effective nuclear charge felt by the valence electrons decreases. This leads to a decrease in the ionisation potential as it becomes easier to remove them from the force field of the nucleus due to a lessening in the effective nuclear charge.
