![]() ![]() A polyatomic ion is just a fancy way of referring to an ion that has more than one atom in it, like the nitrate ion (NO3-) or the sulfate ion (SO4-2) ion. If the anion has more than one element, then you’ve got yourself a polyatomic ion. ![]() For example, the second word in NaCl would be “chloride” and the second word in CaF2 is “fluoride”. If the anion is just one element (as in the case of NaCl or CaF2), just write the name of that element with “-ide” at the end. Here’s how you figure out what word to write down to identify it: The anion is the second thing in the chemical formula. Using these, NaCl has the first word “sodium” and “Li2SO4” has the first word “lithium.” It’s simple! If the cation is the ammonium ion (NH 4 +), just write “ammonium” as the first word.If the cation is a metal, write down the name of the metal.The cation is the first thing in the chemical formula. The first word is the name of the cation (the first ion) and the second word is the name of the anion (the second one). With that totally realistic scenario bouncing around in your head, let’s get started with your stepwise ticket to Namingburg:ġ) Ionic compound names consist of two words. “…and while we’ve got him on the operating table, it wouldn’t be a bad idea to check his titration gland, either.” If you don’t follow these steps, your life will descend into misery and bitterness until you eventually end up having a heart attack when you’re 45. ![]() If you follow these steps, you’ll get everything right and your family will love you. If you’d like to learn to name ionic compounds, follow these steps. Go check out the tutorial for those (links to the right of this page). If you’ve got only nonmetals, and if the ammonium ion isn’t the cation, you’re probably looking at a covalent compound. If you’ll recall the tutorial about ionic compounds, ionic compounds are compounds in which cations (ions with positive charge) are attracted to anions (ions with negative charge) in great big crystals. After all, if you do a great job of naming your ionic compound but the compound is actually covalent, you still won’t get the answer right. In my time as a teacher, probably the most common question people have for me is “What’s the deal with your beard?” The next common question people have for me is “How do I name ionic compounds?” We’ll explore the answer to one of these questions in this tutorial.īefore you can write the names of ionic compounds, it’s important that you make sure you’re actually dealing with an ionic compound. ![]()
