(i) The nucleus of any atom composed of protons and neutrons is positively charged and the electrons revolve around it are negatively charged.
(ii) There is an attraction between the nucleus and electron which act as a centrifugal force for the electrons to keep revolving.
(iii) The electrons should fall into the nucleus due the attraction. But this will not happen because of the Bohr’s theory.
(iv) According to the theory the electrons revolve around the nucleus in specified orbits, he called them as the discrete orbits.
(v) He also stated that the electrons while moving in these orbits do not radiate energy.
(vi) Due to which the electrons will keep on revolving in the discrete orbits because there is no loss of energy from the electrons until any external force is applied.
