MCQ
The energy of a $2p $ orbital except hydrogen atom is
  • A
    Less than that of $s{p^2}$ orbital
  • More than that of $2s$ orbital
  • C
    Equal to that of $2s$ orbital
  • D
    Double that of $2s$ orbital

Answer

Correct option: B.
More than that of $2s$ orbital
b
Atomic orbitals are filled always in the increasing order of their energies. $2s$ orbital is filled first than the $2 p$-orbital.

It means that $2 p$-orbital has more energy than the $2s$-orbital.
