Question

The degeneracy of the level of hydrogen atom that has $-\frac{R_H}{16}$ energy is

• A. 16
• B. 4
• C. 2
• D. 1

Answer 1

Answer: (A)

$E_n=-\frac{R_H}{n^2}$

$\therefore -\frac{R_H}{n^2}=-\frac{R_H}{16}$

That is for fourth subshell



That is $1+3+5+7=16$

$\therefore$ Degeneracy is $16$
