प्रश्न

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?

उत्तर

The energy of electrons is determined by the value of n in the hydrogen atom and by `n + l` in the multielectron atom. Thus for a given principal quantum number the electrons of different orbitals would have different energy.
