Question

electrons revolve around the nucleus in orbitals which have variabls​

Answer 1

Answer:

Nucleus

Explanation:

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy.

Note: Electrons revolve around the nucleus in concentric circular orbits at fixed distance from nucleus. These are stationary orbits and the energy of electrons in these orbits is constant. As long as electrons revolve in these stationary orbits, they do not radiate energy.
