Explanation To draw a correct Lewis structure it is most important to satisfy valency of the elements involved in bonding. The electronic configuration of O is, O = 1s 2 2s 2 2p 4 The number of valence electrons in O is 6 . Thus, total number of valence electrons in O 2 2 − = 2 × 6 − ( − 2 ) = 14 Since, two oxygen atoms are involved, so they form covalent bonding
