Atoms and Elements The Atom Atomic Number and Mass Number Isotopes LecturePLUS Timberlake 1 Atomic Theory ? Atoms are building blocks of elements ? Similar atoms in each element ? Different from atoms of other elements ? Two or more different atoms bond in simple ratios to form compounds ...
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 ...
