Many elements have non-integral atomic masses because

Many elements have non-integral atomic masses because

Many elements have non-intergral atomic masses because (1)the constituents neutrons, protons, and electrons, commbine to give fractional masses (2) they have isotopes (3) their isotopes have nonintergal masses (4) their isotopes have different masses

Explain why elements have fractional atomic masses ?
