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

Options

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

Answer

1

Explanation

For hydrogen the energy order of orbital is " " 1s lt 2s=2p lt 3s=3p=3d lt 4s=4p=4d=4f`.
