Naming chemical compounds can be a bit tricky. One of the biggest problems is that people started naming compounds before they understood what they were! And, the problem just gets bigger as we discover new classes of compounds.
Even naming simple binary inorganic ionic compounds (well ... salts!) can produce enormous headaches.
Well, we've started sorting through some of the mess, starting with a whole let new set of resources for writing the formula of cations and naming cations using the current IUPAC recommendations.
Members should log-in to AUS-e-TUTE to use the new resources, but if you are not a member you can go to the "free-to-view tutorial" at https://www.ausetute.com.au/cations.html
