Question

Q. Not considering the electron spin the degeneracy of second excited state is 9 while the degeneracy of the first excited state of H^ -1 is :-

a) 1
b) 2
c) 3
d) 4​

Answer 1

$\huge\underline{\underline{\mathfrak\red{Answer}}}$

(a) 1

Explanation

For multi electron species (H^-1) first excited state means electron will transfer from 1s to 2s subshell and 2s subshell has only one orbital so degeneracy is 1.
