WebOct 16, 2024 · A Lewis structure is based on the concept of the octet rule, in which atoms share electrons so that each atom has eight electrons in its outer shell. As an example, an oxygen atom has six electrons in its outer shell. In a Lewis structure, these six dots are arranged so that an atom has two lone pairs and two single electrons.
