The History Of Atoms

This timeline relates to the events leading to the development of nuclear weapons which derive destructive energy from the release of atomic energy in nuclear weapons and atomic bombs. At the beginning of the 20th century scientists realized the atom could be split and the atom's elementary building blocks the electron, proton, and neutron were mapped which led to the discovery of nuclear fission transforming the atom into a new and powerful source of energy.
