Answer this :

How did Neils Bohr explain the stability of atom​

Answer 1

In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ... The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump

Answer 2

he said that instead of orbits, the electrons revolved around the nucleus in fixed energy levels or shells.In this way they will not lose energy after revolution

he also said that the level of energy in each orbit is stable and does not change

so if electrons get excited, they will jump up to a higher energy level and start revolving with that energy.

I hope it's clear now about how he explained an atoms stability by giving the concept of energy levels.
