Quizplus · Accepted Answer

The correct symbol for the nitrogen ion is N3-. The superscript - indicates that the ion has gained an extra electron, thus making the total number of electrons 10 (instead of the usual 7). In terms of electron configuration, this would be written as 1s2 2s2 2p6, or in shorthand notation, [He] 2s2 2p6. Looking at the answer choices, the only one with a negative charge on nitrogen is option B, which correctly shows N3-.
