Electrons do not radiate energy while revolving in discrete orbits.

(B) According to Bohr's postulate,electrons revolve around the nucleus in specific,discrete orbits known as stationary orbits. While revolving in these discrete orbits,electrons do not radiate energy. This explains the stability of the atom,as the electrons do not lose energy and fall into the nucleus.
