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
Empire of the Atom is kept alive because one of the atom priests wants to conduct an experiment to see what will happen if the boy, unlike other mutant children, is given the full education of an atom priest. In his teens the mutant boy Clane helps his father win a war with Mars. He also continues his studies while his grandfather, who is Lord Leader, and his tutors protect him from the Machiavellian intrigues swirling around him, especially those of his grandmother Lydia. Reaching his majority, Clane turns his estate into a laboratory where he can test new inventions and machines that he
