1. Chemical Bonds Types of Bonds
Chapter 20
Section 2

2. Ion An atom that has gained or lost an electron
Positive and Negative charges are not balanced

3. Ionic Bond
The force of attraction between the opposite charges of ions in an ionic compound
A transfer of electrons occurs
Compound has a neutral charge

4. EX: Magnesium Chloride
ZERO NET CHARGE

5. Covalent Bond
The attraction that forms between atoms when they share electrons
Molecule – A neutral particle that forms as a result of electron sharing

6. Multiple Covalent Bond
Single Covalent Bond
Multiple Covalent Bond

7. Polar vs. Nonpolar
Polar Molecule  A molecule that has a slightly positive and a slightly negative end
Nonpolar Molecule  A molecule where electrons are shared equally in bonds
