This is video 2 in Chem Jen's 5-video series of naming compounds (Naming Compounds 2: Transition, Multivalent Ionic). This video follows Naming Binary Ionic Compounds and expands Ionic naming to include multivalent and transition metals. If an element is multivalent ( if it has more than one ionic charge) then its charge MUST be indicated using a Roman numeral. For example, Copper can be +1 or +2. If it is +1 you would indicate it by writing Copper (I) _______ and if it is +2 you would indicate it by writing Copper (II) ___________.
Sometimes the charge of the multivalent or transition metal needs to be inferred by the compound. For instance, Fe0 is called iron (II) oxide because oxygen, in group 16, has a -2 charge. This means Fe has to have a +2 charge and that +2 charge is indicated by the Roman numeral (II).
The video includes detailed explanation and samples to work through. Best way to succeed is by practice!
