Ionic Compounds and Naming Conventions

The video tutorial explains how to name the ionic compound lithium fluoride (LiF). It begins by identifying lithium as a metal and fluorine as a non-metal, forming an ionic compound. The tutorial details the process of naming the compound by first writing the name of the metal, lithium, and then the non-metal, fluorine, with the suffix 'ine' replaced by 'ide' to form 'fluoride'. The video also covers writing the chemical formula for LiF, noting that lithium has a +1 charge and fluoride a -1 charge, balancing to zero, thus requiring one of each ion. The tutorial concludes with a summary of the naming and formula-writing process.

What type of compound is formed when lithium and fluorine combine?
