In bohr's model of hydrogen atom
WebOct 7, 2012 · In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, … WebThe Bohr model of a hydrogen atom was proposed by scientist Neils Bohr in the year 1913. According to the Bohr model formula of hydrogen, hydrogen atoms have a positively charged nucleus, which possesses protons, and neutrons. They are surrounded by negatively charged electrons and are seen to orbit around the nucleus in atomic shells.
