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 called on to join him on his quest and provide a way for him to reach Sorcerers' World. Captain Atom appears as one of the central characters in "", a maxi-series that takes place during the wider "Brightest Day" event. At the start of the series, Captain Atom is recruited as part of a massive group of superheroes tasked with hunting down the JLI's founder and Ted Kord's murderer, Maxwell Lord. During an encounter with Max at the Justice League's former New York headquarters, Captain Atom is rendered unconscious alongside Fire, Ice, and Booster Gold. The former Justice League members
