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
Olaf—An Atom he recovers, alone and forgotten by those he has helped. He then moves aimlessly along. Directed by Anthony O'Sullivan and written by William E. Wing, "Olaf—An Atom" was produced by the Biograph Company and released May 19, 1913, in the United States. The drama was released August 4, 1913, in the United Kingdom. The film was retitled "The Wanderer" and re-released by the Aywon Film Corporation, a New York City company formed in early 1919. Aywon reissued films including the Biograph Company short films, which were often lengthened by the addition of intertitles. Olaf—An Atom Olaf—An Atom is a 1913
