J. J. Thomson
J. J. Thomson recieved the Nobel Prize for the discovery of the electron. He also recieve recognition for his work of the conduction of electricity found in gases. -
Ernest Rutherford
Ernest Rutherford became well known for his concept of the nucleus. He studied the inner structure of the atom, which the scattering in the atom led to his concept of the nucleus. -
Isotope comes to existence
In 1912, the existence of isotopes, atoms with a particular chemical element, but with a different number of neutrons, come to be found by Frederick Soddy. -
Bohr Model
The Bohr model was made by Niels Bohr. This model depicts the atom as a small, positively charged nucleus, surrounded by electrons that travel in circular orbits around it. This model is similar to the solar system, with the orbits of the planets around the Sun, -
Nuclear Fission
Nuclear Fission , the splitting of an atom, first was discovered in 1938. Almost 50 years of work studying explosions and nuclear physics came to the discovery of the spliting. -
Nuclear Fusion
The first nuclear fusion experiments were performed in 2009. These reactions were large-scale, being very difficult to pull off.
