The video tutorial explains how to find oxidation numbers for each element in lithium nitride (Li3N). It begins by noting that Li3N is a neutral compound, meaning the oxidation numbers must sum to zero. Lithium, being in group one of the periodic table, has a +1 oxidation number. The video then calculates the oxidation number for nitrogen, ensuring the total equals zero. The tutorial concludes by summarizing the oxidation numbers for each element in Li3N.
