it's by law of inertia like the earth revolving around the sun

Neela's answer is good, if you think of the electron as a particle. Theoretically the moon can keep on revolving around the Earth forever with no loss of energy, as predicted by the law of conservation of angular momentum. There is some energy loss, however, because of tidal friction. But that's not the same thing as a large fraction of the moon's energy leaving every revolution.
Similarly, the electron can keep going round. As long as it was given the right speed originally, it keeps its speed forever without any more energy input.
Unfortunately, the electron-as-particle model fails on many counts, though. A better one treats the electron as a standing wave. Bohr pictured the electron wave going around an orbit and interfering with itself positively.
That model was too simple, and failed too.
Still, the one in use by physicists involves the electron being a wave that dissipates no energy.

The force that make the electron to revolve around a proton is the electrostatic force of attraction between the opposite charges and also the centeripetal force which keeps it moving around it. an electron losses energy when it travels from higher energy level of shell to lower energy level.

those days physics is starting to be to be para-physics and philosophy. no person knows the respond for the easy question the place electron is getting or have been given potential on the initiating. Nature isn't lotto and should no longer be defined by skill of statistics (danger). the two all of us be attentive to what is going on or we don't be attentive to. If electron is moving around nucleus and does no longer pick potential to achieve this (inertia) fer sufficient, yet on the initiating he has have been given commencing potential E=mv2/2 to start moving. the place that potential comes from? If proton has a mass and electron has a mass there is gravity in place attempting to break down electron to nucleus. What retains them aside? Centrifugal rigidity of electron? probable, yet how then we are able to describe circulation of the electrons interior conductor.

The atomic structure answers that question:
------------------------------------------------------------
- The electrons can't be stationary becouse there is nothing that can keep them inplace aginst the electric force puling them to the nucleas
- There is something called Stable orbit, its possible when the electrons r dynamically in motion, here is the explanation:
- Lets take the hydrogen atom as an example (only one electron in the atom).
- There r two forces affecting that electron:
1- Centerpital force (Fc) : which occurs due to the rotating of electron with very high speed (Force that pulls it outside the atom)
2- Attraction force (Fe) : due to the attraction of the electron to the nucleas (force that attract the electron into the nucleas)
- When the two forces r equal, they cancels each other, dynamically stable orbit occurs, so that whats make the electron moves around the nucleas without leaving the atom (due to Fc) nor hitting the nucleas (due to Fe), so it just keep rotating around the nucleas under the action of its velocity

Attraction towards positive nucleus makes electron revolve round it. There is no loss of energy.

the centripetal force reqd 4 revolving around d nucleus is provided by the nuclear force of attraction.these attractive forces are the result of opposite charges on electron and nucleus.since charge is equal and opposite the effect is nullified,there's no loss of energy

This can be due to the centripetal forces acting from the centre once the electrons are set into motion and the another is the forces of attraction .
