This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus. What was Niels Bohr’s most important discovery? Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation. In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. What did Bohr contribute to the atomic theory? Bohr’s model explained why atoms only emit light of fixed wavelengths, and later incorporated the theories on light quanta. Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.
