(i) Discrete orbit was the term given by Neils Bohr to specify the imaginary path of the electrons moving around the nucleus without losing energy.
(ii) For the atom to be stable it is important that it has the minimum energy and be electrically neutral.
(iii) For this the electron have to be constantly revolving around the nucleus without radiating or gaining any energy.
(iv) Neils Bohr gave the postulate that electron will only revolve in the paths or orbits in which it will not radiate any energy and hence the atom will be stable.
(v) So, the special orbits that are present inside the atom in which the electron revolves is given the term of ‘discrete orbit’.
