1. Bonding

2. Learning Goals I am learning to form and name ionic compounds.
I am learning to form and name molecular compounds.

3. Bonding
Goal:
To achieve a full octet (full valence shell)

4. Ionic bonding

5. Ionic Bonds Happens between a metal and a non-metal.
Involves the transferring of electrons

6. Metals Metal loses electrons to become a cation (+ve charge)
# of protons > # of electrons

7. Non-metals Non-metal gains electrons to become an anion (-ve charge)
# of protons < # of electrons

8. Attraction
Since opposite charges attract, metal and non-metal bond together.
We can use Lewis diagrams to demonstrate this …

9. Examples
1: Draw the Lewis Dot Diagram and name the compound formed between Lithium and Fluorine.
2: Draw the Lewis Dot Diagram and name the compound formed by Calcium and Chlorine.

10. Naming Name the metal first
Change the ending of the non-metal to “ide”

11. Molecular bonding

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

13. Draw the Lewis Dot diagram and name the molecule formed by 1 Nitrogen and 3 Hydrogen.
Draw the Lewis Dot diagram and name the molecule formed by 1 Carbon and 4 Hydrogen.

14. 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

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

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