Final answer:
Step 3 of writing Lewis structures with the octet rule is to think about the result. At this step, you consider whether each atom in the molecule or ion follows the octet rule.
Step-by-step explanation:
Step 3 of writing Lewis structures with the octet rule is to think about the result. At this step, you consider whether each atom in the molecule or ion follows the octet rule. For example, if you are writing the Lewis structure for a molecule of H2O, the oxygen atom has two pairs of bonding electrons and two lone pairs, while each hydrogen atom has one bonding pair of electrons. This follows the octet rule for both oxygen and hydrogen.
