Why do subshells in a multi-electron atom have different energies?

Options

  1. ADue to the magnetic quantum number
  2. BDue to the spin quantum number
  3. CDue to the mutual repulsion among electrons
  4. DDue to the attraction between electrons and protons

Correct answer

C. Due to the mutual repulsion among electrons

Step-by-step solution

The main reason for different energies of subshells in multi-electron atoms is the mutual repulsion among the electrons.
