WebAccording to Bohr Atomic model, a small positively charged nucleus is surrounded by revolving negatively charged electrons in fixed orbits. He concluded that electron will have more energy if it is located away from the nucleus whereas the electrons will have less energy if it located near the nucleus. The postulates given by Neils Bohr are ... WebAug 12, 2014 · 1 Answer. Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits. Bohr built upon Rutherford's model of the atom. In Rutherford's model most of the atom's mass is concentrated into the centre (what we …

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).
