Identify degenerate orbitals from following for hydrogen atom.
Identify degenerate orbitals from following for hydrogen atom.
$1 \mathrm{~s}$ and $2 \mathrm{~s}$
$1 \mathrm{~s}$ and $2 \mathrm{p}$
$2 \mathrm{~s}$ and $2 \mathrm{p}$
$3 \mathrm{~s}$ and $2 \mathrm{p}$
Solution
An increasing order of energies of orbitals in the hydrogen atom is given by:
$1 \mathrm{~s} < 2 \mathrm{~s}=2 \mathrm{p} < 3 \mathrm{~s}=3 \mathrm{p}=3 \mathrm{~d} < \ldots$
Thus, in hydrogen atom $2 \mathrm{~s}$ and $2 \mathrm{p}$ are degenerate orbitals.
