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...
