1. Molecular Bonding

2. Learning Goal
I will be able to form and name molecular compounds.

3. Why Bond!? Atoms like to have 8 electrons in their outer ring.
Stable octet

4. Molecular Bonding Happens between two non-metals.
Involves the sharing of electrons.
The sharing of electrons is called a covalent bond.

5. Draw the Lewis Dot diagram and name the molecule formed by Nitrogen and Hydrogen.
Draw the Lewis Dot diagram and name the molecule formed by Carbon and Hydrogen.

6. Naming Covalent Compounds
You write the name of the first element and the second element second element s ending is changed to ’s ending is changed to “-ide”
We use prefixes to state the number of each element present (never put “mono” on the first element)
One = mono-
Two = di-
Three = tri-
Four = tetra-
Five = penta

7. Example
Provide names for the following compounds:
N2O4
H2O
CO2

8. Example Provide formulas for the following names: nitrogen trihydride
phosphorus pentaoxide
dicarbon tetraoxide

9. Practice Set Write Names Write Formulas antimony tribromide

10. Learning Goal Revisited
I will be able to form and name molecular compounds.

11. Building Molecules Activity
Pg 265 will be helpful for common names and usages
