Niels Bohr. In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Scientists at the Niels Bohr Institute, University of Copenhagen have been instrumental in developing a 'hands-on' answer to a challenge intricately linked to a very fundamental principle in physics: Heisenberg's Uncertainty Principle. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In 1911 did experimental work going on in the Cavendish Laboratory under J.J. Thomson's guidance and In 1912 he was at work in Rutherford’s laboratory in Manchester. Het model van Bohr is daarmee het eerste model met kwantumtheoretische aspecten. His father was Christian Bohr, a brilliant physiology professor who would later be nominated twice for a Nobel Prize. Bohr modificeerde het atoommodel van Rutherford door het invoeren van kwantiseringen, gebaseerd op de theorie van Planck over de kwantisering van straling. Het atoommodel van Bohr is een in 1913 door Niels Bohr geïntroduceerde theorie die de opbouw van atomen beschrijft. To figure out what was happening inside the atom, he had to study the way atoms behaved and then come up with a model that explained what was happening. Voor zijn theorie kreeg Bohr … Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr.The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models. Among all the major scientists of the twentieth century, Niels Bohr may have most wanted to be considered a philosopher. He was the second of three children in a prosperous, upper-class family.
