Niels Bohr was born on October 7, 1885, in Copenhagen, Denmark
With Adolf Hitler's rise in power, Bohr was able to offer German Jewish physicists refuge at his institute in Copenhagen, which in turn led to travel to the United States for many. Once Denmark became occupied by Nazi forces, the Bohr family escaped to Sweden, with Bohr and his son Aage eventually making their way to the United States. Bohr then worked with the Manhattan Project in Los Alamos, New Mexico, where the first atomic bomb was being created.
Neil Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
The Bohr model, introduced by Niels Bohr in 1913, depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus—similar in structure to the solar system, but with attraction provided by electrostatic forces rather than gravity.
This picture is the Electron Orbit model which shows that the further away from the nucleus in the atom the more energy.
This model also shows how the Electron Orbit model goes up in energy when you go up in orbit level.
The Bohr model has been discontinued, but the quantum theory remains the same.
Main Points of the Bohr Model
- Electrons orbit the nucleus in orbits that have a set size and energy.
- The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
- Radiation is absorbed or emitted when an electron moves from one orbit to another.
