1. What is the value of the period table?
2. Using what we learned in the lesson about different types of compounds, shapes, and intermolecular forces, why do you think H2O, NaCl, and CO2 are in different phases at room temperature?
3. Predict whether H2O or H2S would have a higher boiling point. Explain your reasoning.
5. Why is a Roman numeral needed for iron compounds but not for compounds containing magnesium?
