Explanation:
J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube.
Thompson - Electrons
Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
Bohr - Electron energy levels
Rutherford was the first to discover that atoms have a small charged nucleus surrounded by largely empty space, and are circled by tiny electrons.
Rutherford - Nucleus
Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
