WebUsing classical physics, Niels Bohr showed that the energy of an electron in a particular orbit is given by En = − ℜhc n2 where ℜ is the Rydberg constant, h is Planck’s constant, c is the speed of light, and n is a positive integer corresponding to the number assigned to the orbit, with n = 1 corresponding to the orbit closest to the nucleus. Web12 de ago. de 2014 · Bohr's most significant contribution was explaining the model using the quantification energy. He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
