1.	A rrange s, p an d d subshells o f a shell in the in creasin g o rd er of effective n u clear charge (Z_("eff")) experienced by th e electron p resen t in them .
Answer» Solution :s-orbital is spherical in shape, it shields the electrons from the nucleus m ore EFFECTIVELY than p-orbital which in TU RN shields m ore effectively than d-orbital. So, the effective nuclear charge `(Z_(eff))` experienced by electrons PRESENT in them is `d lt p lt s`
