Solution

The correct option is C 9
We know,
$E_{n} = - \frac{R_{H}}{n^{2}} = - \frac{R_{H}}{9}$
$∴ n = 3$

Since n=3, there are 3 subshells, but, for H like systems, for any energy level n, the degeneracy is given by $n^{2}$

So the degeneracy of the energy level will be $n^{2} = 3^{2} = 9$

What is the degeneracy of the hydrogen atom energy level that has the energy (−RH9)? (Where RH is Rydberg energy constant)

The correct option is C 9We know, En=−RHn2=−RH9 ∴n=3 Since n=3, there are 3 subshells, but, for H like systems, for any energy level n, the degeneracy is given by n2 So the degeneracy of the energy level will be n2=32=9
