Lewis structure for NO2-1

Answer 1

The dot structure for nitrogen dioxide starts with a N atom in the center with a double bond to the O to the left and a single bond to the right. The doubly bonded O has two pair of dots, and the single bonded O has three pair. Finish with a single dot on the N atom.

Answer 2

The Lewis structure for NO2^- can be drawn as follows: Nitrogen is the central atom with one lone pair and two oxygen atoms double bonded to it. The overall charge of the ion is -1, so we also add an extra electron to the structure. The formal charges on the nitrogen and oxygen atoms should be taken into consideration when drawing the Lewis structure.
