Niels bohr contribution to atomic theory9/11/2023 For example, physicists currently conclude that light is both a wave and a stream of particles - two apparently mutually exclusive properties - on the basis of this principle. Bohr's institute served as a focal point for theoretical physicists in the 1920s and '30s, and most of the world's best known theoretical physicists of that period spent some time there.īohr also conceived the principle of complementarity: that items could be separately analyzed as having several contradictory properties. In 1922, Bohr was awarded the Nobel Prize in physics "for his services in the investigation of the structure of atoms and of the radiation emanating from them". In 1916, Niels Bohr became a professor at the University of Copenhagen, and director of the newly constructed "Institute of Theoretical Physics" in 1920. Niels Bohr and Albert Einstein debating quantum theory at Paul Ehrenfest's home in Leiden (December 1925). Bohr also introduced the idea that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy. On the basis of Rutherford's theories, Bohr published his model of atomic structure in 1913, introducing the theory of electrons traveling in orbits around the atom's nucleus, the chemical properties of the element being largely determined by the number of electrons in the outer orbits. He then studied under Ernest Rutherford in the Victoria University of Manchester in England. His brother was Harald Bohr, a mathematician and Olympic soccer player who played in the Danish national team Niels Bohr was a passionate soccer player as well, and the two brothers played a number of matches for Akademisk Boldklub.īohr received his doctorate from Copenhagen University in 1911 under Christian Christiansen. His father, Christian Bohr, was professor of physiology at the University of Copenhagen, while his mother, Ellen Adler Bohr, came from a wealthy Sephardic Jewish family prominent in Danish banking and parliamentary circles. Niels Bohr was born in Copenhagen, Denmark in 1885. He received the Nobel Prize for Physics for this work in 1922. The principle of complementarity: that items could be separately analyzed as having several contradictory properties.Much work on the Copenhagen interpretation of quantum mechanics.The idea that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy (this became the basis for quantum theory).The theory that electrons travel in discrete orbits around the atom's nucleus, with the chemical properties of the element being largely determined by the number of electrons in each of the outer orbits.The electron's orbital angular momentum is quantized L=nħ.Bohr is widely considered one of the greatest physicists of the twentieth century. Niels (Henrik David) Bohr ( Octo– November 18, 1962) was a Danish physicist who made fundamental contributions to understanding atomic structure and quantum mechanics.
