1911. That same 12 months he traveled to Cambridge, Britain, to study nuclear physics underneath the British

physicist Sir Frederick John Thomson, but he soon relocated to Manchester to work with another

Uk physicist, Ernest Rutherford.

Bohrs theory of atomic framework won him the Nobel Prize in physics in 1922. It was

published in papers between 1913 and 1915. His work drew on Rutherfords nuclear type of the

atom, in which the atom is seen as a compact nucleus surrounded by a swarm of much lighter weight

electrons. Bohrs atomic style made use of mess theory as well as the Planck constant, which is

the ratio between quantum size and radiation frequency. The model demonstrates that an atom emits

electromagnetic radiation only if an electron in the atom jumps from quantum level to

one other. This model added greatly to future innovations of theoretical atomic physics.

In 1916 Bohr came back to the School of Copenhagen as a professor of physics, and in

1920 he was produced director of the universitys new Institute to get Theoretical Physics.

There Bohr developed a theory relating quantum numbers to huge systems stated in this article classical

laws, and made different major input to assumptive physics. Bohrs work helped lead to the

concept that electrons exist in covers and that the bad particals in the outermost shell can determine an

atoms chemical real estate.

In 1939 Bohr convinced physicists at a scientific meeting in the United States in the

importance of, Otto Hahns and Fritz Strassmans, experiments. This individual later indicated that

uranium-235 is a particular isotope of uranium that goes through nuclear transmutation. Bohr then

returned to Denmark, where he was forced to remain after the German career of the nation

in 1940. Eventually, however , he was asked to escape to Sweden. From Sweden the Bohrs

traveled to England and eventually to the Us, where Bohr joined in your energy to

develop the first atomic blast, working by Los Alamos, New South america, until the 1st bombs

detonation in 1945. This individual opposed finish secrecy from the project, yet , and terrifying the

implications of this ominous new development. He desired international control.

In 1945 Bohr returned for the University of Copenhagen, in which he immediately commenced

working to develop peaceful uses for atomic energy. He arranged the initial Atoms for Peace

Seminar in Geneva, held in 1955, and couple of years later this individual received the first Atoms for Peace

Award. In 1997 the International Union of Natural and Applied Chemistry declared that the

chemical substance element with the atomic amount 107 will be given the official name bohrium (Bh), in

honor of Niels Bohr.
