WebNov 15, 2024 · What particles determine the mass number of an atom Why is the mass number always a whole number? The two subatomic particles, neutrons, and protons reside inside an atom’s nucleus. Thereby, Mass Number = Number of protons + Number of neutrons. These proton’s and neutron’s numbers are always whole numbers. 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…
