Rounded atomic mass of helium
WebAtomic Mass = Protons + Neutrons. We round the atomic mass to the nearest whole number, 4. Since we already determined that Helium has two protons, that means: 4=2+Neutrons. There must be 2 Neutrons in one atom of Helium WebAtomic Number – Protons, Electrons and Neutrons in Helium. Helium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus.Total number of …
