1.	Arrange s, p and d sub-shells of a shell in the increasing order of effective nuclear charge (Z_("eff")) experienced by the electron present in them.
Answer» SOLUTION :s-orbital, being spherical in shape, SHIELDS the electrons from the nucleus more effectively than p-orbital which in turn shields more effectively than d-orbital. Hence, the increasing order of effective nuclear CHARGE `(Z_("eff"))` experienced by the electrons PRESENT in them is: `d lt p lt s`
