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 … http://alpha.chem.umb.edu/chemistry/ch115/Mridula/documents/UnitsMeasurementUncertaintyandSignificantFigures_Answers.pdf
