Atom of Ernest Rutherford, bombarded a metal foil with alpha particles to observe how they scattered. They expected all the alpha particles to pass straight through with little deflection, because Thomson's model said that the charges in the atom are so diffuse that their electric fields could not affect the alpha particles much. However, Geiger and Marsden spotted alpha particles being deflected by angles greater than 90°, which was supposed to be impossible according to Thomson's model. To explain this, Rutherford proposed that the positive charge of the atom is concentrated in a tiny nucleus at the center of the atom.
Captain Atom Captain Atom himself when he first became Monarch. Mon-El appears and helps Captain Atom escape, taking him to the Justice League's satellite, where the League members declare that they are going to bring him to justice for his actions as Monarch. After a struggle with the League, Captain Atom tells them what he can remember. The League reminds him he was a hero who once saved the planet. He feels he has changed from the man he once was, and that he needs to go back to the magic world to make right what he has done. The Shadowpact are
