Helium atom −54.41776311(2) eV. The total ground state energy of the helium atom is −79.005151042(40) eV, or −2.90338583(13) a.u. Helium atom A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution to the Schrödinger equation for the helium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and
Atom (Ray Palmer) to restore the natives of Kandor to their full height, but is instead tricked into reviving a twisted Kryptonian cult, whose leader proceeds to crush Palmer and Kandor. Other re-imaginings of the Atom include an appearance in "League of Justice", an Elseworlds story portraying the Justice League in a "The Lord of the Rings"-type story where the Atom was recast as a wizard/fortune teller called "Atomus The Palmer". In "", Ray Palmer worked with a science consortium whose members at one point included Thomas Edison and Nikola Tesla. In "JLA: Rock Of Ages", the Atom is part of what remains
