Imagine removing one electron from


Imagine removing one electron from He4 and He3. Their energy levels, as worked out on the basis of Bohr model will be very close. Explain why.


The energies of He4 and He3 will be very close according to the Bohr model because both have 1 electron as in case of the hydrogen atom and the nucleus is 4 times

heavier than the H-atoms. Therefore, the stability of these atoms remains close to the H atom and so is their energy levels.
