ELECTRONIC TRANSITION IN HYDROGEN ATOM In 1913, it was Neils Bohr who solved many of the problems at the time by proposing that the electron revolves around the nucleus of the atom with a definite fixed energy in a fixed path, without emitting or absorbing energy. According to Bohrs theory, electrons of an atom revolve around the nucleus on certain orbits, or electron shells. Each orbit has its specific energy level, which is expressed as a negative value.The figure below shows the electron energy level diagram of a hydrogen atom.
