which model of the atom had electrons travelling in circular orbits?
However, since this does not occur, this model failed as well. 5) Bohr's Atomic model. This model represents the electrons orbiting the nucleus of an atom in circular orbits. These electrons had specific orbits and distinct orbital levels. Electrons that gained energy would jump to higher energy levels and become excited, and as they jumped back down to the ground state, they would emit that energy.
