  1. 1. Connect the Dots Living By Chemistry Unit: Smells Investigation II – Lesson 3
  2. 2. What do you think? <ul><li>The lines in this structural formula represent bonds. </li></ul><ul><li>What do you think a bond is? </li></ul>
  3. 3. Covalent Bonds <ul><li>A covalent bond is a connection that forms between two atoms when those atoms are share a pair of electrons between them. </li></ul>
  4. 4. Lewis Dot Structures
