Electrons go on the diagram What goes on the bohr diagram? Bohr's model incorporated the then nascent quantum theory in that the distance between electron orbits was fixed, or quantized, and electrons traveling from one orbit to another absorbed or emitted these quanta of energy. Rutherfords model states that most of the atom consists of an empty space and the center of the atom contains a positively charged nucleus surrounded by negatively charged electrons, resulting in continuous electron spectrum.
