Let's talk about how to write chemical formulas for ionic compounds so what this means is we're gonna start with a chemical name like magnesium chloride and learn the steps that we have to go through to take this chemical name and use it to write a chemical formula like mgcl2 okay let's start with our first example lithium oxide so when I'm doing these kind of problems the first thing that I want to do is find both these elements on the periodic table I'm using this kind of weird version of the periodic table that I just wrote out I left out a lot of the elements because they're not important for what we're doing here and I thought that are kind of distracting but don't be confused this really is no different from the periodic table that you probably have in your book it's just that it's missing a lot of the elements anyway lithium I want to find that it's right here Li and oxide oxide is just another word for oxygen it's what we call oxygen when oxygen has a charge I'm going to talk a little bit more about that later anyway oxide is just another word for oxygen and oxygen is over here they're on opposite sides of the periodic table and check this out too there's this big thick staircase that separates lithium from oxygen what's a staircase doing well if you remember the staircase separates the metals on this side of the periodic table from the nonmetals on this side of the periodic table so lithium is a metal and oxygen is a non-metal this is important because we have a metal and a nonmetal connected together and that means that we're dealing with an ionic compound ionic compounds are always...
