Ionic Compounds and Their Properties

The video tutorial explains how to write and name the formula for the ionic compound Rb3N, known as rubidium nitride. It begins by identifying rubidium as a metal and nitrogen as a non-metal, forming an ionic compound. The tutorial details the naming process, emphasizing the use of 'ide' for nitrogen. It also covers the charge balancing required for the compound, with rubidium having a +1 charge and nitrogen a -3 charge, necessitating three rubidium atoms to balance the charge. The video concludes with a summary of the naming and balancing process.
