1. Formula writing

2. Binary compounds Two elements only End in “ide”
Binary ionic-metal and nonmetal
Binary molecular – 2 nonmetals

3. Binary ionic compounds
Group A metal – name normal
Second element changed to an “ide” ending

4. Binary ionic compounds

5. Binary molecular coumpounds
Always two nonmetals
First nonmetal name normal
Second nonmetal always ends in “ide”
Must identify the numbers hanging down (subscripts)
