Ionic Compounds and Their Properties

The video tutorial explains how to name and write the formula for the ionic compound MgO. It begins by identifying MgO as a binary ionic compound, consisting of a metal and a non-metal. The tutorial outlines the steps to name such compounds: first, write the metal's name as it appears on the periodic table, then write the non-metal's name with an 'ide' ending. For MgO, this results in the name 'magnesium oxide'. The video also covers how to derive the chemical formula from the name, noting the charges of magnesium and oxygen ions and how they balance to form MgO.
