1. Chemical Bonds

2. 2 Types of Chemical Bonds 1. Ionic 2. Covalent

3. Ionic Bonds Ionic Bonds- the force of attraction between the opposite charges of ions. The giving and taking of electrons (+ with -) Ions- Atoms that have a charge

4. Ex: Magnesium Oxide Mg +2 O -2 MgO =Mg O Ex: Magnesium Chloride Mg +2 Cl -1 2 MgCl =Cl Mg Cl........ Ionic Bond.........

5. Covalent Bonds Covalent Bond- The attraction that forms between atoms when they share electrons. The sharing of electrons (+ with + or - with -) Molecule- neutral particle formed from covalent bond

6. Ex: Diatomic Chlorine (Cl 2 ) Cl -1 Cl -1 Cl -1 Cl -1 Cl Cl = Cl Cl Ex: Diatomic Hydrogen (H 2 ) H +1 H +1 HH = H H.......... Covalent Bond
