    Assertion: Energy of the orbitals increases as 1s lt 2s = 2p lt 3s = 3p lt 3d lt 4s =4p =4d =4f lt …… in a hydrogen atom. Reason:Energy of the electron depends completely on principal quantum number.

    STATEMENT-1: For hydrogen orbital energy increases as 1s lt 2s lt 2p lt 3s lt 3p lt 3d lt 4s lt 4p... STATEMENT-2: The orbital with lower (n+l) value has lesser energy and hence filled up first.
