SO2 Lewis Structure   Answer: here is the definition of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that form of diagram where we present the complete 18 valence electrons of SO2 as dots , or dots and also dashes(-).In Lewis structure,it is typical that a bonding pair of 2 electrons have the right to be presented by  dash(-) or dots(●●) but a lone pair of 2 electrons is displayed by dots<●●>. In SO2 Lewis structure,there space two double bonds that space going indigenous the atom sulphur come oxygens. In SO2 Lewis framework ,there are entirely five lone bag of electrons.The each  oxygen has actually two lone pairs of electrons and also the sulphur atom has actually one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule yet the sulfur atom don't monitor the octet rule.It has much more than eight electrons.
