Mass number for helium
WebFor example, Helium has atomic number two. This means all He atoms have two protons. However, the number of neutrons can vary for different atoms of Helium (and therefore … WebMass numbers of typical isotopes of Helium are 3; 4. Atomic Mass of Helium Atomic mass of Helium is 4.0026 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
