Ionic Compounds and Their Properties

The video tutorial explains how to name and write the formula for the ionic compound MgF2. It begins by identifying MgF2 as a binary ionic compound composed of a metal and a nonmetal. The tutorial then outlines the steps to name the compound: first, by naming the metal (magnesium) and then the nonmetal (fluorine), replacing the ending with 'ide' to form 'fluoride'. Finally, it explains how to determine the formula by balancing the ionic charges of magnesium and fluorine to achieve neutrality, resulting in the formula MgF2.
