Names and Formulas for Molecular Compounds (Covalent Bonding) Formulas – recall how we have used the valence electron information to know how many of each element we need to satisfy the octet rule.

What do we call this?

Dihydrogen Monoxide

Prefixes for Molecular Names 1 Mono- 2 Di- 3 Tri- 4 Tetra- 5 Penta- 6 Hexa- 7 Hepta- 8 Octa- 9 Nona- 10-Deca

Ionic Compounds- Precipitate Lab Combine 1 to 2 drops of each ionic compound to be reacted. Describe both the precipitate and the aqueous solution. Give the name and balanced formula for the precipitate. Clean up you materials and get your data signed.
