Question

Which of the following is a postulate of Bohr’s model that explains why electrons do not lose energy as they revolve around the nucleus?​

Answer 1

As long as an electron revolves in a particular orbit, the electron does not lose its energy. Therefore, these orbits are called stationary orbits and the electrons are said to be in stationary energy states.

Answer 2

Answer:

According to postulated of Bohr's atomic model, the electron has a definite amount of energy and electron does not lose or gain while moving in the orbit.

Note:

Electrons revolve around the nucleus in concentric circular orbits at fixed distance from nucleus.  These are stationary orbits and the energy of electrons in these orbits is constant. As long as electrons revolve in these stationary orbits, they do not radiate energy.
