    • Describe nuclear structure in terms of protons, neutrons, and electrons
    • Recognize the role of mass defect and binding energy for nuclei in atomic masses
    • Explain trends in the relative stability of nuclei
    • Identify common modes of radioactive decay
    • Write and balance nuclear equations
    • Describe half-life and common radiometric dating techniques
    • Explain the organization of elements in the periodic table and predict their general properties based on their location within the periodic table
    • Symbolize the composition of molecules using molecular and empirical formulas
    • Represent the bonding arrangement of atoms within molecules using structural formulas
    • Define ionic and molecular (covalent) compounds
    • Predict the type of compound formed from elements based on their location within the periodic table
    • Determine formulas for simple ionic compounds
