Question

If the number of electrons in the inner shells increase then 1) Ionisation potential increases 2) Screening effect increases 3) Shielding effect decreases 4) Nuclear attraction on outer electrons increases

Answer 1

Answer:

Screening effect increases

Explanation:

Screening effect or shielding effect is the effect of reduction of force of attraction between nucleas and valence elctrons by between electrons in inner shells...so the ionisation energy decrease since it is easy to remove outermost electron from its valence shell.
