Lewis Dot Structures

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

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

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

Example Step 1: Step 2: 7 Step 3: Step 4: Cl
