Why do the electrons stay in orbit around the nucleus? (What force pulls them in?)

Why is electron revolving around the nucleus of an atom?
Like gravity acting on planets, an electromagnetic force attracts the orbiting electron to the nucleus. Classical physicists wondered that the electron didn't run out of energy. Niels Bohr solved this mystery by introducing quanta, discrete energy states in which electrons may stably persist.

Hope this helps mark me as brainiest please please

Very hard to understand
