Ionic Compounds and Their Properties

The video tutorial explains how to name the ionic compound Ba3P2 as barium phosphide. It begins by identifying barium as a metal and phosphorus as a non-metal, forming an ionic compound. The process involves writing the metal's name as it appears on the periodic table and modifying the non-metal's name by replacing its ending with 'ide'. The tutorial also covers how to derive the formula from the name by recognizing the ionic charges of barium and phosphorus, ensuring the charges balance to zero. The video concludes with a brief closing statement.
