Hydrogen atom has only one electron, so mutual repulsion between electrons is absent. However, in multielectron atoms mutual repulsion between the electrons is significant. How does this affect the energy of an electron in the orbitals of the same principal quantum number in multielectron atoms?

Options

  1. AThe energy of an electron in a multielectron atom with the same principal quantum number is higher compared to
  2. BThe energy of an electron in a multielectron atom with the same principal quantum number is lower compared to
  3. CThe energy of an electron in a multielectron atom remains the same as in a hydrogen atom.
  4. DThe energy of an electron in a multielectron atom cannot be determined.

Correct answer

A. The energy of an electron in a multielectron atom with the same principal quantum number is higher compared to

Step-by-step solution

Correct Option is : (A) The energy of an electron in a multielectron atom with the same principal quantum number is higher compared to a hydrogen atom.
