Steps to naming :
Steps to naming Step 1- Identify binary covalent compounds
Two different non-metals bonded together
Step 2- Identify how many of each element in the formula Ex: H2O, CO2, CO
2 Hydrogen, 1 Oxygen
1 Carbon, 2 Oxygen
1 Carbon, 1 Oxygen
Steps to naming :
Steps to naming Step 3- Assign the correct prefix to indicate how many of each element. The first element gets no prefix if there is only one. Second element has –ide suffix
1 = mono-
2 = di-
3 = tri-
4 = tetra-
5= penta-
6 = hexa-
7 = septa-
8 = octa-
9 = nona-
10 = deca- H2O
Dihydrogen monoxide
CO2
Carbon dioxide
CO
Carbon monoxide

NO CRISS-CROSSING!!!!
Prefix number is the subscript in the formula Tetraphosphorus decoxide
P4O10
Dinitrogen trioxide
N2O3
To practice… :
To practice… Look for the remaining binary compounds on your packet- if they contain only non-metals, do them! Also complete the formula writing of any names that contain prefixes.
