One S atom (with six valence electrons) and two O atoms (each with six valence electrons) makes a total of 6 2(6)=18 valence electrons that should be shown in your structure. Check that each of your structures shows exactly 18 electrons. Remember that a line represents two electrons and a pair of dots represents two electrons.
1.Draw a Lewis structure for SO2 in which all atoms obey the octet rule. Show formal charges. 2 Draw a Lewis structure for SO2 in which all atoms have a formal charge of zero. Explicitly showing the zero charges is optional.
