Niels Bohr investigated the structure of the atom and won the Nobel Prize in Physics in 1922 for discovering the Bohr model. He developed the liquid drop model of the atomic nucleus, proposed the idea of complementarity and identified the U-235 isotope essential for nuclear fission. After fleeing the German invasion of Denmark, he worked on the development of the atomic bomb at Los Alamos in the United States.Continue Reading
The Bohr model proposes electrons orbit the nucleus because of electromagnetic forces rather than gravity. Because of this difference, electrons do not collapse into the nucleus but travel from one orbital shell to another as energy levels change.
As a Danish citizen, Bohr resisted involvement with German nuclear power research and aided many Jewish scientists in their escape from Nazi power. He fled Denmark in 1943 and eventually made his way to London, where he was involved with experiments for a viable nuclear fission bomb.
Bohr was adamant that atomic research should be shared, causing Winston Churchill to view him as a security risk. He organized the Atoms for Peace Conference in Geneva in 1955.
Bohr's son Aage Niels Bohr also contributed to the world of physics. Aage won the Nobel Prize in Physics in 1975.Learn more about Inventions
Niels Bohr and Ernest Rutherford were the scientists who developed the planetary model of the atom, also referred to as the Bohr model. In 1913, Bohr published a theory, which was based on a previous theory of Rutherford’s.Full Answer >
To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number. After that, place the neutrons and the protons in the nucleus, and draw the electrons in their designated shells.Full Answer >
The idea of electron shells was developed by Niels Bohr in his 1913 model of the atom, which places electrons into stable orbits around the nucleus. The Bohr model was a modification of the Rutherford model, which did not require that electrons move in orbits of fixed size and energy.Full Answer >
A Bohr model of Yttrium is a representation of an atom of Yttrium. Yttrium was discovered by Johann Gadolin in 1794. It is named after a town in Sweden.Full Answer >
