SO2 Lewis Structure   Answer: below is the meaning of SO2 Lewis structure. SO2 Lewis framework (sulfur dioxide electron dot structure) is that type of diagram where we present the complete 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is usual that a bonding pair of two electrons deserve to be shown by  dash(-) or dots(●●) however a lone pair of 2 electrons is shown by dots<●●>. In SO2 Lewis structure,there space two dual bonds that room going indigenous the atom sulphur come oxygens. In SO2 Lewis framework ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and also the sulphur atom has one lone pair the electrons. In SO2 Lewis structure ,the oxygen atom follow the octet rule yet the sulfur atom don't monitor the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone bag of electrons.Here,each oxy
