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
BASIC Atom BASIC Atom "Basic Atom" refers to a line of self-contained microcontrollers from Basic Micro. Like the Basic stamp, the Basic Atom line is based upon various microchips pre-programmed with an interpreter, making it easy to change "programs", as they are only "data" being interpreted. A compiler converts a high level language into the interpretive "code" which is then loaded in as data, and run. Basic Atom chips may be added to other projects via the familiar Dual in-line package style, or the higher density TQFP. One small Basic Atom Pro is implemented as a Single in-line package thus taking very
