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...

Atoms and Isotopes 1 Activity: Atoms and Isotopes Why? Atoms and isotopes are identified by the numbers of protons, electrons, and neutrons that they contain The number of protons, electrons, and neutrons in atoms determines the chemical properties of the elements .A knowledge of the number of protons and electrons in an atom will help you understand how atoms combine to form molecules Identify the composition of atoms in terms of protons, neutrons, and electrons Use atomic symbols to represent...
