Niels Bohr
Niels Bohr is primarily known for his pioneering work in the field of atomic theory. Born on October 7th, 1885, in Copenhagen. His father Christian Bohr, a famous physiologist and mother, Ellen, recognized his great abilities and special gifts early in life that they provided Niels with the best education possible. After graduating High school first in his class, Bohr studied at the University of Copenhagen in1903. Bohr won a gold medal from the Royal Danish Academy of Sciences for his theoretical analysis of vibrations of water jets as a means of determining surface tension. Bohr received his Master's degree from the University of Copenhagen in 1909 and his doctorate in 1911 with a thesis Studies on the electron theory of metals. Also at the university he met his future wife, Margrethe N
Only a limited number of orbits with certain energies are allowed. The electron in a hydrogen atom travels around the nucleus in a circular orbit. Allowed orbits have their electron's angular momentum be an integral multiple of Planck's constant divided by 2pi. Niels Bohr proposed a model for the hydrogen atom that explained the spectrum of the hydrogen atom. The energy of the radiation emitted or absorbed is exactly equal to the difference between the energies of the orbits. They were married on August 1st, 1912. ------------------------------------------------------------------------**Bibliography**. This is the quantization of orbits using Planck's hypothesis. In 1911, Rutherford had postulated an atomic model which described the hydrogen atom as a small heavy nucleus surrounded by an electron in a fixed circular orbit around it. Radiation can occur only when the electron jumps from one orbit to another. Radiation is absorbed when an electron jumps to a higher energy orbit and emitted when an electron falls into a lower energy orbit. The Bohr model was based on the following assumptions: The Bohr Model of the Atom 1.
