1. Chemical Bonds
Part 3

2. bond formed by the sharing of electrons
COVALENT BOND
bond formed by the sharing of electrons

3. Happens when Two non-metals are joined together
When the atoms share electron pairs
Octet rule is still in place
Examples; O2, CO2, C2H6, H2O, SiC

4. Covalent bonds Oxygen Molecule (O2)
Atoms share electrons to fill outer shells
Oxygen Atom
Oxygen Atom
Oxygen Molecule (O2)

5. Watch it Happen
Covalent Bonds

6. Diatomic Elements Some atoms cannot be alone
They must be combined with something so are often paired with another of the same:
H O F Br I N Cl
H O F Br I N Cl2
These are always covalent

7. Naming Covalent Compounds
See the handout that Ms. D has for you. You can put this straight into your notebook as the notes.
