Neutral Monism Overview & Examples | What is Neutral Monism? When we name their compounds, we have to specify which oxidation number is involved. Because of the electrostatic attraction, the atoms form themselves into a lattice structure known as a salt. The four rules for naming ionic compounds are: Why is it important to have rules for naming compounds? Sign up to highlight and take notes. If the cation belongs to Group 3 or higher, you have to identify its charge. So if I said, "iron oxide", I haven't specified the charge for the ion, which makes determining the formula very difficult. Naming covalent compounds differs from naming ionic compounds, since covalent compounds have a numbered prefix added to the names of elements to specify the amount of each element. Now that we've covered the rule, let's put them to use and look at some examples to help you practice what you have just learned! If you try and say Ca3(PO4)2 out loud as "see-ay-three-pee-oh-four-two" it's a bit of a mouthful. In this video, we'll walk through this process for the ionic compound calcium bromide. How are ionic compounds named? (APEX!) A. A number is given in $$. You first write the name of the metal, lithium, and then write the name of the nonmetal, adding an -ide ending so that sulfur becomes sulfide.
