What are the Bohr's postulates?

1 . There is a positively charge nucleus at the centre of atom around which the electron move in a circular orbit . The necessarycentripetal force is provided by the coulomb's force of attraction exerted by positively charge nucleus on the negatively charge electrons. 2 . The electrons moves in a certain discrete orbits called stationary orbit for which the total sngular momentum pf moving electrons is the integral multiple of the h/2 pie 3 . When electron jump from one stationary orbit of higher energy(Ei) to another energy orbit of lower energy (Ef) .It radiates energy as a single photon of frequency v Ei -- Ef = hv , this equation is called bohr's frequency condition.
