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.
Mister Atom Mister Atom can fly and fire nuclear blasts from his hands (In the Golden Age, at least, lead is impervious to these blasts). Mister Atom appeared in an issue of the "Justice League Unlimited" comic book, where Doctor Sivana was trying to rebuild him with the help of a local gang. Atom and Sivana were eventually defeated by the Justice League, particularly Vibe. The character also appeared several times in the all-ages comic series "Billy Batson and the Magic of Shazam!"
