Web16 de ene. de 1997 · The nucleus of a hydrogen atom is a single proton. The nucleus of a helium atom is two protons and two neutrons. The mass of four protons is 6.690x10-24g. The mass of a helium nucleus is 6.643x10-24g, 0.7% lighter. Einstein (1905) demonstrated equivalence of mass and energy, E=mc2. Eddington (1920's) suggested that the sun … The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total mass of at…
