Text Solution

Verified by Experts

According to Bohr's theory of hydrogen atom, electrons revolve around the nucleus is some fixed orbits and during its motion, an electron does not lose energy. For this reason, these orbits are known as "electronic orbits at stationary states".
When an electron stays in such an orbit, it does not remain stationary at all. Had it been so, the electron, being attracted by the nucleus would have fallen on the nucleus. the electron always remains in motion so as to overcome the influence of the nuclear attractive force.
