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

Options

  1. A3 s, 3 p and 3 d -orbitals all have the same energy.
  2. B3 s and 3 p -orbitals are of lower energy than 3 d -orbital.
  3. C3 p -orbital is lower in energy than 3 d -orbital.
  4. D3 s -orbital is lower in energy than 3 p -orbital.

Correct answer

A. 3 s, 3 p and 3 d -orbitals all have the same energy.

Step-by-step solution

The hydrogen atom has the configuration 1 s and 3 s, 3 p and 3 d -orbitals will have same energy with respect to 1 s -orbital.
