Please refer to the example image to answer. You must use CER, claim-evidence-reasoning. Make sure that your answer is CLEAR and explained well. Claim is your answer to the question. Evidence is from the image and reasoning is your explanation.  Proper evidence for all Lewis structures include: Most electronegative atom must be in the center. Octet of electrons surrounding each atom. Total number of electrons depicted equals same total number of valence electrons from each participating atom. Make sure to refer to the example image because it shows the correct Lewis structures. The question you're answering is about the students drawing of CH20.
