WebJun 1, 2011 · Bohr and the ‘old’ quantum theory. In 1911 Bohr completed his doctoral dissertation on the classical electron theory of metals. Developed by Sir J.J. Thomson and Lorentz, the theory explained electrical, magnetic and thermal properties of metals in terms of the motions of free electrons. Although Bohr made no use of the quantum hypothesis ...

WebIn 1913, Bohr proposed that electrons exist in discrete orbits based on their energy. When an electron jumps from one orbit to a lower orbit, it gives off energy in the form of a photon. The quantum theory of light -- the idea that light exists as tiny packets, or particles, called photons -- slowly began to emerge. optical probe for meter reading price
