Bohr model is a system consisting of small, dense nucleus surounded by orbting electrons. The electrons travel in defined circular orbits around the nucleus for which orbital angular momentum is an itnegral multiple of h/(2pi) . While rotating in allowed orbits the electrons does not raidate energy. Electromagneitc radiations are emitted when the electrons jumps from a higher orbit (E_(n_i)) to a lower orbit (E_(n_f)) When an electron jumps from higher to lower orbit energy is:

Bohr model is a system consisting of small, dense nucleus surrounded by orbiting electrons. The electrons travel is defined circular orbits around the nuclues which orbital angular moementum is an integral multiple of h/(2pi) . While rotating in allowed orbits (stationary orbits) the electron does not radiate energy. electromagnetic radiations are emitted when the electron jumps from a higher orbit (E_(ni)) to a lower orbit (E_(nf)) . The total energy of the electron in an atom is negative. It suggests that
