Neils+Bohr-1922

Niels Henrik David Bohr was born October 7, 1885 in Copenhagen, Denmark. He died at the age of 77 on November 18, 1962. Niels Bohr discovered the structure of atoms in 1913 while being a professor at the University of Copenhagen. He also founded the Institute of Theoretical Physics in 1921. He won the Nobel Prize for his discovery. Before becoming a physicist, Bohr was a philosopher and mathematician but soon changed his major to being a physicist after winning the gold medal in a competition sponsored by the Royal Danish Academy of Sciences and Letters. Bohr studied under Ernest Rutherford at the University of Manchester in England. Bohr was also a part of the Manhattan Project but went under the name Nicholas Baker for security reasons. He almost got arrested for wanting to go public with what the Manhattan Project was creating.

Bohr introduced the theory of electrons traveling in orbits around the atom's nucleus. He determined that the chemical properties of the element was largely determined by the number of electrons in the outer orbits. He also introduced the idea that an electron could drop from a higher-energy orbit to a lower one, emitting a photon, or light quantum, of discrete energy. This became the basis for quantum theory. Bohr's discovery helped better understand the idea of what an atom looks like and the properties that an atom has. It also helped with the understanding of how light is produced through chemical reactions and the movement of electrons from their orbital shells.  Bohr's model of the atom
