1 Niels Bohr suggested that electrons in an atom were restricted to specific orbits around the atoms nucleus. 2  Bohr argued that an electron in a given orbit has a constant energy, thus he named these orbits energy level.
Bohr's mentor was Ernest Rutherford who said that atoms were made up of a nucleus with electrons orbiting around it. Bohr expanded Rutherford's theory by defining the paths that electrons follow. Bohr also won the Nobel Prize in 1922 for his atomic model.
