Helium atom 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 wavefunction of the atom. The quantum mechanical description of the helium atom is of special interest, because
Ariel Atom Atom 4. The limited production Ariel Atom 500 V8 featured a V8 engine. The all new Ariel Atom 4 is the latest Atom featuring a new turbocharged 2.0l engine that is used in the Honda Civic Type R with 3-stage boost. The Ariel Atom features a prominently visible chassis (i.e., an exoskeleton, no roof or windows, a small optional windscreen) and a drag coefficient of 0.40. The Atom began as a student project by Coventry University transport design student, Niki Smart. Known then as the LSC (Lightweight Sports Car), it was developed at the university in 1996 with input and
