Electron present in the nth shell of an element is most effectively shielded by:
(n-1)th orbital
(n-2)th orbital
(n-3)th orbital
none of these
As we learnt
Comparison of screening power -
An electron present in the n th orbital is more effectively shielded by (n-1)th orbital while the same electron is not effectively shielded by the other electron present in the same orbital.
