Niels bohr atomic model

Niels Henrik David Bohr 7 October — 18 November was a Danish theoretical physicist who made foundational contributions to understanding atomic structure and quantum theory , for which he received the Nobel Prize in Physics in Bohr was also a philosopher and a promoter of scientific research.

How did niels bohr discover the bohr model

Bohr developed the Bohr model of the atom , in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level or orbit to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity : that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles.

The notion of complementarity dominated Bohr's thinking in both science and philosophy.

Niels bohr nationality

He predicted the properties of a new zirconium -like element, which was named hafnium , after the Latin name for Copenhagen, where it was discovered. Later, the synthetic element bohrium was named after him because of his groundbreaking work on the structure of atoms. During the s, Bohr helped refugees from Nazism. After Denmark was occupied by the Germans , he met with Heisenberg, who had become the head of the German nuclear weapon project.

In September word reached Bohr that he was about to be arrested by the Germans, so he fled to Sweden. From there, he was flown to Britain, where he joined the British Tube Alloys nuclear weapons project, and was part of the British mission to the Manhattan Project. After the war, Bohr called for international cooperation on nuclear energy.

Niels was a passionate footballer as well, and the two brothers played several matches for the Copenhagen-based Akademisk Boldklub Academic Football Club , with Niels as goalkeeper. Bohr was educated at Gammelholm Latin School, starting when he was seven.
