The degeneracy of hydrogen atom that has energy equal to $\frac{- R _{H}}{9}$ is (where, $R_{H} =$ Rydberg constant)

Options:

Answer:

Solution:

The energy is given as, $E = - \frac{R _{H}}{9} ... (i)$ We know that, $E_{n} n^{2} n = - \frac{R _{H}}{n ^{2}} ... (ii) = 9 = 3$ When $n = 3, l = 0, 1, 2$ $(3 s, 3 p, 3 d sub-shells)$ Orbitals present (i.e., degeneracy), $3 s = 1, 3 p = 3, 3 d = 5$ Total number of orbital present $= 3 + 1 + 5 = 9$
