Answer:
Bohr's model.
Explanations:
According to Neil Bohr, electron can orbit the nucleus in a special orbit and at different energy level around the nucleus of an atom. Some of his other propositions include the fact that;
- Electron can jump from one energy level to another and absorbing or emittibg radiation.
- There are discrete nature of energy levels for electrons
Hence we can conclude that the model that described the atom like a solar system, in which the electrons orbited around the nucleus is the Bohr's model.
