Ionic Compounds and Fluorine

The video tutorial explains how to name the ionic compound BaF2. It begins by identifying the elements involved: barium, a metal, and fluorine, a non-metal. The process of naming involves replacing the ending of fluorine with 'ide' to form barium fluoride. The video also covers writing the chemical formula, noting that barium has a 2+ charge and fluorine a 1- charge, requiring two fluorine atoms to balance the charge of one barium atom. The tutorial concludes with a summary of the naming process.
