SPS4. Students will investigate the arrangement of the Periodic
Table. a. Determine the trends of the following: number of
valence electrons, types of ions formed by representative
elements, location of metals, nonmetals, and metalloids, and
phases at room temperature. b. Use the Periodic Table to predict
the above properties for representative elements.
