Drawing Lewis Structures

Lewis Structures Find out which group your element is in. This will tell you the number of valence electrons your element has. You will only draw the valence electrons. www.chem4kids.com

O Lewis Structures Write the element symbol. Oxygen is in the 6th group, so it has 6 valence electrons. ALWAYS place first 2 electrons together as a pair Then place 1 electron on each side Then start pairing Check your work. Do you have the correct number of valence electrons? O

Lewis Structures – Exception Carbon Family Write the element symbol. Carbon is in the 4th group, so it has 4 valence electrons. Place 1 valence electron on each side C
