Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
