misslittlescience.weebly.comBohr went on to propose that the negative particles (electrons) orbited the nucleus much like the planets orbit the sun. Today the atomic model is very similar to Bohr’s model. The modern atomic model, the Wave model, does not have exact orbits like Bohr did. Instead the modern model has a scatter region surrounding the nucleus where an

cimss.ssec.wisc.eduLet us investigate the development of the Bohr atomic model briefly. In 1913, Bohr postulated that: (a) the angular momentum of the electrons in their circular orbits about the nucleus are quantized, mvr = nh/2π , where m is the electron mass, v the velocity, r the radius, n the quantum number, and h Planck's

ncert.nic.inAccording to the Bohr atomic model, in an isolated atom the energy of any of its electrons is decided by the orbit in which it revolves. But when the atoms come together to for m a solid they ar e close to each other . So the outer orbits of electrons from neighbouring atoms would come very close or could even overlap.
