Hydrogen atom (non relativistic) hydrogen atom was solved for the first time within Feynman's path integral formulation of quantum mechanics. This work greatly extended the range of applicability of Feynman's method. Hydrogen atom A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. In everyday life on Earth, isolated hydrogen atoms (called "atomic hydrogen") are extremely rare. Instead, hydrogen tends to combine with other atoms
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
