Write down the postulates of bohr atomic model

Answer 1

Dear Student,

THE POSTULATES OF BHOR'S MODLE:-

1) electrons revolve round the nucleus only in certain permissible circular orbits , also called shells.

2)each orbit is associated with a definite energy.

3) the energy of an electron remains constant as long as it revolves in a given orbit.

4)when electron absorbs energy, it jumps from a low -energy level to a high-energy level.

5)but, electron at higher energy level is unstable . so, it jumps from higher energy level to lower energy level and gives out energy
