Question

Number of degenerates orbitals in second shell of he+ ion is ????

Answer 1

Answer:

Explanation:

Thus energy of 2s orbital is same as of 2p. The first excited state of He⁺ is (1 s 0 2 s 1) or (1 s 0 2 p x 1) or (1 s 0 2 p y 1) or (1 s 0 2 p z 1). Since all of them have the same energy, we can see it is 4 fold degeneracy.
