WebOne atomic mass unit is equal: 1u = 1.66 x 10 -24 grams. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. For 12 C, the atomic mass is exactly 12u since the atomic mass unit is defined from it. WebAtomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of subatomic particles present in the atom.
