WebName: Helium Symbol: He Atomic Number: 2 Atomic Mass: 4.002602 amu Melting Point: -272.0 °C (1.15 K, -457.6 °F) Boiling Point: -268.6 °C (4.549994 K, -451.48 °F) Number of Protons/Electrons: 2 Number of Neutrons: 2 Classification: Noble Gas Crystal Structure: Hexagonal Density @ 293 K: 0.1785 g/cm 3 Color: colorless Atomic Structure 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 …
