1. Recognize the important subdivisions of the periodic table: periods, groups (families), metals, and nonmetals.
2. Use the periodic table to obtain information about an element.
3. Describe the relationship between the electronic structure of an element and its position in the periodic table.
4. Write electron configurations for atoms of the most commonly occurring elements.
5. Know the meaning of the octet rule and its predictive usefulness.
6. Use the octet rule to predict the charge of common cations and anions.
7. Utilize the periodic table and its predictive power to estimate the relative sizes of atoms and ions, as well as relative magnitudes of ionization energy and electron affinity.
8. Use values of ionization energies and electron affinities to predict ion formation.
