  1. Lewis Dot Structures

  2. Valence Electrons • Valence electrons are the most important electrons because they determine reactivity • They are used in bonding • What are valence electrons? • Electrons on the outer most energy level • How can we easily find out the number of valence electrons? • Group Number

  3. Representing Valence Electrons • Lewis Dot Structures • Because valence electrons are the most important, these are the only electrons we will show

  4. How to Draw Lewis Dot Structures • Step 1: Write the element’s symbol • Step 2: Determine the number of valence electrons • Step 3: Start drawing a dot on the right side of the symbol • Step 4: Draw the rest of the dots by moving counter clockwise and putting 1 on each side

  5. Example • Step 1: • Step 2: • 7 • Step 3: • Step 4: Cl
