Question

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

• A. in the orbit
• B. in the nucleus
• C. in the atom
• D. in the molecule

Answer 1

The correct option is A in the orbit

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.
