WebThis came to be known as the planetary model. The other ground-breaking theory stated that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy (Wikipedia, 2006). This became a basis for quantum theory. The basis of Bohr’s theory was rooted in Max Plank’s theory of light.
