WebBohr and Bury proposed the following rules for electron distribution. Rule 1: The maximum number of electrons present in a shell is given by the formula 2n 2, where 'n' is the shell number. Rule 2: Each energy level or electron shell is further divided into sub shells. The maximum number of electrons that can be accommodated in each sub shell is 8. WebJan 6, 2024 · Niel Bohr’s Atomic Theory states that – an atom is like a planetary model where electrons were situated in discretely energized orbits. The atom would radiate a photon when an excited electron would jump down from a higher orbit to a lower orbit. The difference between the energies of those orbits would be equal to the energy of the photon. randy hepler
