Which of the following statements in relation to the hydrogen atom is correct?

Options

A. 3s-orbital is lower in energy than 3p-orbital
B. 3p-orbital is lower in energy than 3d-orbital
C. 3s and 3p orbitals are of lower energy than 3d orbital
D. 3s, 3p and 3d orbitals all have the same energy.

Answer

D

Explanation

In a hydrogen atom, 3s, 3p and d orbitals will have same energy as all orbitals belonging to the same shall have same energy in hydrogen atom.
