Why are the energy levels of He4 and He3, as calculated using the Bohr model, very close to each other upon removing one electron from each?

Options

  1. ADue to the similar atomic structure of both helium isotopes
  2. BBecause of the identical electronic configuration of He4 and He3
  3. CResulting from the nuclear charge overshadowing the electron's contribution
  4. DAttributed to the quantum mechanical similarities between He4 and He3

Correct answer

C. Resulting from the nuclear charge overshadowing the electron's contribution

Step-by-step solution
