This video tutorial explains how to determine the oxidation number of nitrogen in nitrogen monoxide (NO), also known as nitric oxide. It begins by stating that the oxidation numbers of nitrogen and oxygen in NO must add up to zero since it is a neutral molecule. Oxygen typically has an oxidation number of -2, so nitrogen must have an oxidation number of +2 to balance it out. The video emphasizes the importance of understanding that oxygen is almost always -2 and that in neutral compounds, the oxidation numbers sum to zero. Dr. B concludes the video by summarizing the key points.
