By the end of this unit students will be able to:

  • Classify the components of a periodic table (period, group, metal, metalloid, nonmetal, transition).
  • Infer the physical properties (atomic radius, metallic and nonmetallic characteristics) of an element based on its position on the Periodic Table.
  • Infer the atomic size, reactivity, electronegativity, and ionization energy of an element from its position on the Periodic Table.
