# Why do electrons around nucleus radiate light according to classical physics

As I navigate through physics stackexchange, I noticed Electron model under Maxwell's theory.

Electrons radiate light when revolving around nucleus? Why is it so obvious?

Note that I do not know anything about quantum mechanics - and I just want classical stories.

First of all we all should know the meaning of the phrase "the electron is accelerating." It does not mean that $a=\mathrm{d}v/\mathrm{d}t$. The accelerating electron means that the electron is changing its electric field. Obviously no electromagnetic radiations will be produced during orbital motion of the electron because the electron doesn't radiate during orbital motion. Radiation will be emitted or absorbed only during transition between the energy states.
