Niels Bohr born: october 7,1885 Died: november 18 1962
In 1913, Niels Bohr proposed a theory for the hydrogen atom , based on the quantum theory that some physical quantities only take discrete values.Bohr model explained why atoms only emit light of fixed wavelengths , and later incorporated the theories on light quanta.Called quantum theory , it proposed that electrons circle the nucleus following the classical laws but subject to limitations, such as the orbits they occupy and the energy they lose as radiation when they jump from orbit. -

This principle was announced in 1928.The complementarity principle implies that phenomena on the atomic and subatomic scale are not strictly like large scale particles or waves.He recognized the need for mathematical formalism of quantum mechanics to be embedded in the rationally coherent conceptual framework if it was to serve as the core of scientific theory.In his principle it states on a atomic level physical phenomena expresses itself differently depending on the experiment setup. -

Niels Bohr formulated the compound nucleus model. It explained nuclear reactions to a two staged process.The bombarding particle becomes an integral part of a new , unstable nucleus called a compound nucleus. The compound nucleus then loses its energy in different ways,such as a losing neutron or emmiting gamma rays.The compound nucleus model explains that nuclear reactions induced by relatively low energy bombarding particles.The model was the most prominent description of the process. -

In the mechanism of nuclear fission it is the first fully worked out theory of nuclear fission and it laid the groundwork for for atomic bombs and hydrogen bombs.HE devoloped the liquid drop model in nuclear physics to explain the mechanism of fission.In the model,the structure of nucleus was like a liquid drop of incomprehinsible liquid.Like a drop could be deformed from it basic spherical shape to form new two new drops , a large atomic nucleus , could fall apart to form two new atomic.
