1. Covalent Bonding

2. Single Bonds
Instead of giving and taking electrons, atoms share electrons
If the atoms share one pair of electrons they form a single covalent bond H H H H + H H

3. Double Bonds
Double bonds need to share more than one pair of electrons to attain stable noble-gas electron configurations. O O O O +

4. Triple Bonds
Bonds that involve three shared electron pairs. N N N N +

5. Coordinate Covalent Bonds
If an atom provides both of the electrons it is called a coordinate covalent bond. C O C O +

6. O O O Resonance Structures
Structures that occur when it is possible to write two or more valid electron dot formulas that have the same number of electron pairs O O O

7. Bond Polarity
If one end on a molecule is more negative than the other the molecule is polar
H-Cl O
H H

8. Electric Field
If polar molecules are placed in an electric field, the negative ends will orient themselves toward the positive plate
