Bohr’s model of the atom
Based on:
Rutherford: nuclear model of the atom (p+ : center, e- : orbit)
Balmer-Rydberg’s positive integer quantum numbers
Planck’s and Einstein’s quantized energy concept (and photon)
1- Classical physics does not apply to particles of atomic or sub-atomic
dimensions.
2- The energy of an electron in a hydrogen atom is quantized (allowable
energy level).
3- The atom changes from a stationary state to another stationary state
only by absorbing or emitting photon (energy).
4- An hydrogen atom radiates energy only when the electron jump from
one allowed stationary state to a lower energy stationary state.
