What is Atomic Number and Mass Number? Atomic 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 ...
How are atomic numbers and mass numbers represented? Atomic number is shown on the periodic table. It is the number with a decimal on the periodic table and is often listed below the symbol for the atom. Mass number is not shown on the periodic table but is often found when elements are...
