Science SC2015 (2015) Grade: 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.
