Question

How and why electrons revolve around the nucleus?

Answer 1

Electrons should move in such a way that is feasible for atoms as well as for electrons.

N.So electron moves in a circular path around nucleus having centripetal force which balances the electrostatic force of attraction.

And this is only possible when the electron revolves around the nucleus.

Hence it revolves around the nucleus!

Electrons revolve around the nucleus in fixed orbits or shells called energy levels. Electrons rotate around the nucleus in one or more energy levels.

These are represented as 1, 2, 3 i.e. an integer ‘n’ or as K, L, M,
