| What do Binary Compounds always end in? | -ide |
| What is the FIRST question for naming a compound? | Is the formula Binary (2 elements) or Not Binary? |
| What is the SECOND question for naming a compound? | Is the 1st element a Nonmetal or Metal? |
| What is the THIRD question for naming a compound? | Is the Metal's charge Known or Unknown? |
