Diatomic Different Round 2 - Covalent
Are the atoms the same (O2) or are they different (CO2)? Diatomic Exist paired in nature Go to 7, make a 7, and don’t forget H N2, O2, F2, Cl2, Br2, I2, H2 Different Uses prefixes First element must be >1 for prefix Second element always gets a prefix Round 2 - Covalent
6
Diatomic Different Round 3 – Covalent Rules Name the element Done!
Name first element, use prefix if >1 Use prefix with second element Add a suffix –ide to second element Done! Different Round 3 – Covalent Rules
