1 - Explain the relationship of an element's position on the periodic table to its atomic number. (3.1)

2 - Use the periodic table to identify metals, nonmetals, metalloids, families (groups), periods, and valence electrons. (3.1 & 3.2)

3 - Relate the position of an element on the periodic table to its electron configuration and compare its reactivity with other elements. (3.3)

4 - Identify trends on the periodic table (ionization energy, electronegativity, and relative size of atoms and ions). (3.4)
