Cobalt and Nitride Compounds

This video tutorial explains how to name the compound Co3N4. It begins by identifying cobalt as a transition metal and nitrogen as a non-metal. The video then demonstrates how to name the compound by first naming the metal and then the non-metal, modifying the non-metal's suffix to 'ide'. The tutorial further explains the importance of considering the charges of the ions involved, calculating the charge of the nitride ion and determining the charge of cobalt to ensure a net charge of zero. Finally, the video concludes with the complete name of the compound: cobalt(IV) nitride.
