Oxidation Numbers in NASCN

The video tutorial explains how to determine the oxidation numbers for each element in the compound NaSCN. It starts by identifying the compound as neutral, meaning the oxidation numbers must sum to zero. Sodium, being in group one, has a +1 oxidation number. Nitrogen, the most electronegative, is assigned -3. Sulfur, slightly more electronegative than carbon, is given -2. An equation is set up to solve for carbon's oxidation number, resulting in +4. The video concludes by summarizing the oxidation numbers for NaSCN.
