Naming Compounds Overview
We just covered a lot of material, so it's now time to take a part of this section and just overview what we have learned. The first question is, can you tell an ionic compound verses a covalent compound? Let's find out by doing this sample problem.
| Problem 5.6 |

| Problem: Is CaO ionic or covalent? After deciding, name the compound by the systematic naming method (learned in this chapter, review if you don't know how to name).
Plan: We need to look at a periodic table in order to determine if the compound is ionic or covalent. Remember that a metal and a non metal make up an Ionic compound (a salt) and that a nonmetal and a nonmetal make up a covalent compound. By looking at the periodic table, we see that Ca and O is a metal with a nonmetal. Thus, this is an ionic compound. Answer: CaO is an ionic compound and the systematic name for the compound is Calcium Oxide. |
Hopefully you were able to distinguish the difference between a covalent and an ionic compound. If not, you MUST learn this. You cannot continue until you can distinguish the difference. If that was easy, good job! Let's name another one
| Problem 5.7 |

| Problem: Is SO2 ionic or covalent? After deciding, name the compound by the systematic naming method (learned in this chapter, review if you don't know how to name).
Plan: Just as above, we need to decide if this is ionic or covalent and then name it. Answer: SO2 is covalent and is named Sulfur dioxide according to the covalent naming rules. |
