[SC2015] PS8 (8) 1 :
1 ) Analyze patterns within the periodic table to construct models (e.g.,
molecular-level models, including drawings; computer representations) that
illustrate the structure, composition, and characteristics of atoms and molecules.
[SC2015] PSC (9-12) 1 :
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] CHEM (9-12) 1 :
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] CHEM (9-12) 3 :
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
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.
