Electrons moving in a circle would be accelerating, would lose energy, and would therefore not be able to maintain their orbits.
Atomic models are designed to determine the nature of the atom. There have been several atomic models whose ultimate aim have been to underscore the interaction between the particles that compose the atom.
The atomic models include;
The main problem of the Planetary system model (Rutherford model) of the atom is that electrons moving in a circle would be accelerating, would lose energy, and would therefore not be able to maintain their orbits.
