1. Select a tag.<br />
a. Are you a positive (+) or negative (-) ion<br />
b. Are you a metal, metalloid, or non-metal<br />
c. Record your info into the data table 3 times, for the 3 different bonds you will make.<br />

a. In the data table, write your partner’s element and charge.<br />
b. Categorize their element as a metal, metalloid, or non-metal.<br />
3. Write the compound into the data table. Criss-Cross your oxidation numbers to make them<br />
subscripts. Reduce if needed. (Remember, the positive ion is written first.)<br />
4. Determine the name of your new compound with the –ide ending.<br />
5. Find a new partner.<br />
