Available Electrons: 18Create the Lewis structure of NO2- using the following steps. NOTE: do only the step asked for in each part and then click Check–don't work ahead to solve the final structure.Step 5. Examine the structure. If it is correct, press Check. If the central atom has fewer than eight valence electrons, introduce multiple bonds. (In this activity assume that only C, N, O, P, and S typically participate in multiple bonds.) Change a single bond to a multiple bond by deleting one or more lone pairs on a terminal atom and dragging a multiple bond between that atom and the central atom.
