Draw the Lewis Structure for SO2, then Draw the complete molecule (dots and lines) of NO2...

Interpretation - 

To draw the Lewis structure for SO₂ and then Draw the complete molecule dots and lines of NO₂  - 

Introduction - 

Lewis structure is that structure which is actually a representation of valence electron in the molecule which we shows by the dots . These dots are the Lewis electron and those electron shows bonding between two atoms shows line.
