For more practice and better understanding, you can try other lewis structures listed below. An outline of how to detemine the "best" Lewis structure for an example, NO 3- is given below: 1. 32 - 26 = 6 electrons short, thus 6 electrons must be shared, 6 shared electrons/ 2 electrons per bond = 3 bonds. Therefore, place tellurium in the center and bromines on either side. The number should be equal to the number of electrons in result 2. Chemists usually indicate a bonding pair by a single line, as shown here for our two examples: In CHM 110, you should always use lines to represent bonds. Connect the two atoms with one single bond .
