Atomic+Discoveries+from+1915+to+1950

James Chadwick 1891-1974

Sir James Chadwick discovered the neutron of the atom in 1932. This discovery was important because it helped with the development of fission in terms that the neutron is unaffected by charge and can best split other atoms. this also allowed for the creation of elements in laboratories that are heavier than uranium.

Sir Chadwick was an English noble laureate in physics.

Niels Bhor 1885-1962

Based on Rutherford's model of he atom, Bhor developed the planetary model of the atom, in which the atoms orbit around the nucleus. He submitted his idea in 1913 and earned the Nobel Prize in 1922.



During WWII Bhor fled to New Mexico and helped scientists develop the first atomic bomb.

Werner Heisenberg 1901-1976

Heisenberg is the founder of quantum mechanics. He also is the founder of the uncertainty principle, which is when you more about something speed and direction, the less you know about the object itself.

He also helped Germany in WWII with his leading role in fission research.
