A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...
