Question

what are the postulates of Bohr's atomic model

Answer 1

$\bf\huge\underline{Answer :-}$

The following were the postulates put forward by Neil Bohr :-

• Out of innumerable number of possible orbits surrounding the nucleus, the electron rotates only in certain fixed, selected or permissible orbit.

• As long as the electron rotates in one of these selected orbit, it neither radiates nor absorb any energy.

• Electron may jump from one permissible orbit of lower energy to that one of higher energy and thereby a definite quantum of energy is absorbed or vice versa.

Answer 2

Answer:

$\huge\bold\pink{ANSWER:-}$

The Bohr model postulates that electrons orbit the nucleus at fixed energy levels. Orbits further from the nucleus exist at higher energy levels. When electrons return to a lower energy level, they emit energy in the form of light.
