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 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
