1. Covalent bonds Covalent Bonds- A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms. Covalent bonds share electrons Ionic bonds transfer electrons

2. Lewis Dot diagrams and covalent bonds Lewis dot diagrams can easily show how atoms are bonded to each other. Lets look at how to make water. O+H H 2 O

3. Examples Cl 2 HClNH 3 CH 4 PCl 3 C 2 H 6

4. Double and Triple bonds With covalent bonds atoms can for double and triple bonds with each other. For this to happen atoms will share more than one pair of electrons.

5. examples The creation of CO 2 C + O CO 2 N2N2

6. With your partner try these C 2 H 4 CS 2 C 2 F 2 CHNC 2 H 2
