Notes I. What makes atoms different? A. Atoms of one element have the same number of protons (the atomic number) 1. An atom may have different numbers of neutrons, and remain the same element 2. Atoms with different neutrons are called Isotopes

II. Periodic Table (page 328). A II. Periodic Table (page 328) A. Information on the periodic table continues to evolve as new elements are identified 1. Atomic number 2. Atomic Mass 3. Chemical Symbol 4. Chemical name 5. Group and period 9
