1. Covalent Compounds
Two non-metals

2. For each compound, which one is the metal? NO

3. How is the bond formed?

4. Covalent Compounds
A covalent compound is one in which electrons are SHARED. 
Involve NON-METALS only.  

7. What are these called?
CO2 CO

8. Naming Covalent Compounds
State the name of each element and use a prefix to determine how many of each atom there are in the formula.
Change the ending of 2nd element to ide.
Do not write a prefix for the first element if there is only one atom. 
Do not reduce: N2O Not NO
