How was Bohr able to explain the stability of an atom?

Explanation

According to Bohr.s atomic model, each orbit or shell is associated with a definite amount of energy, and hence, they are also called energy levels. As long as the electron revolves in a particular orbit, the electron does not lose energy. Therefore, these orbits are called stationary orbits and the electrons are said to be in stationary energy states. When an electron moves from lower-energy level to higher-energy level, it absorbs energy from an external source and gives out energy while jumping from a higher-energy level to a lower-energy level. Thus, he explained the stability of an atom.
