Ionic Compounds and Charges

The video tutorial explains how to name the compound NH4_3N as ammonium nitride. It begins by identifying NH4 as the ammonium ion, a polyatomic ion, and N as nitrogen. The tutorial details the charges of the ions, with ammonium having a +1 charge and nitrogen forming a -3 charge, leading to the formation of the nitride ion. Despite being nonmetals, the compound is treated as ionic due to the presence of these ions. The tutorial also covers how to write the formula from the name by balancing the charges to achieve a net charge of zero. The video concludes with a summary of the naming process.
