As we know that , for doing any work we require energy
and energy will consumed in doing work !!!
But , in case of Atoms, how the electon ( s ) are continuously moving around nucleus without losing energy , if electron lose energy then why doesn't it collapse with nucleus of atom

Dear.... here is the answer ☺
⭐According to classical physics, whenever a charge is accelerated, it must radiate energy. The planetary model of the atom says that electrons are in orbit around the nucleus in stable orbits. An electron which is in orbit around the nucleus is accelerating, because even though the magnitude of its velocity does not change, the direction keeps changing. So, as it is constantly accelerating, it follows that it must continuously keep radiating energy, and as it loses energy, the radius of its orbit keeps reducing and eventually it would fall into the nucleus.
⭐ Bohr’s model ,Bohr said why electrons doesn’t fall into nucleus.
Niels Bohr in his model said that The electrons can only orbit stably, without radiating, in certain orbits (called by Bohr the "stationary orbits") at a certain discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy levels. In these orbits,the electron’s acceleration does not result in radiation and energy loss as required by classical electromagnetics.
Hope it helps you out ⭐^_^⭐

This problem was explained by Neil Bohrs, He explained that electrons will move in a particular path(which they call as orbits or orbitals) without radiating energy (means at a fix energy).
So we can say that electrons will move only in a fixed energy level shells called orbit or orbitals.
On moving on that orbital it have a constant angular momentum which is equal to nh/2π
here h is plancks constant.
