Alabama Course of Study Alignments and/or Professional Development Standard Alignments:

SC (9-12) Physical Science
1. Recognize periodic trends of elements, including the number of valence electrons, atomic size, and reactivity.
  • Categorizing elements as metals, nonmetals, metalloids, and noble gases
  • Differentiating between families and periods
  • Using atomic number and mass number to identify isotopes
    SC2015 (9-12) Physical Science
    1. Use the periodic table as a model to predict the relative properties and trends (e.g., reactivity of metals; types of bonds formed, including ionic, covalent, and polar covalent; numbers of bonds formed; reactions with oxygen) of main group elements based on the patterns of valence electrons in atoms.
    SC2015 (9-12) Chemistry
    1. Obtain and communicate information from historical experiments (e.g., work by Mendeleev and Moseley, Rutherford's gold foil experiment, Thomson's cathode ray experiment, Millikan's oil drop experiment, Bohr's interpretation of bright line spectra) to determine the structure and function of an atom and to analyze the patterns represented in the periodic table.
    SC2015 (9-12) Chemistry
    3. Use the periodic table as a systematic representation to predict properties of elements based on their valence electron arrangement.
    a. Analyze data such as physical properties to explain periodic trends of the elements, including metal/nonmetal/metalloid behavior, electrical/heat conductivity, electronegativity and electron affinity, ionization energy, and atomic-covalent/ionic radii, and how they relate to position in the periodic table.
    b. Develop and use models (e.g., Lewis dot, 3-D ball-and-stick, space-filling, valence-shell electron-pair repulsion [VSEPR]) to predict the type of bonding and shape of simple compounds.
    c. Use the periodic table as a model to derive formulas and names of ionic and covalent compounds.
