उत्तर

Bohr model is applicable for hydrogen atom-and some lighter atoms in which a single electron revolves around a stationary nucleus of positive charge Ze (called hydrogen-like atom). If we remove one electron from He4 and He3, atoms contain one electron and become hydrogen-like atoms. Now we can apply the Bohr model to define the energy levels.
