Naming and Charges of Iron Compounds

The video tutorial explains how to name the compound FeF3. It begins by identifying Fe as a transition metal and F as a non-metal, following specific naming rules. The metal, iron, is named first, followed by the non-metal, fluorine, with 'ine' replaced by 'ide'. Since iron is a transition metal, its charge must be specified. Fluorine has a charge of -1, and with three fluorine atoms, the total negative charge is -3. Therefore, iron must have a charge of +3 to balance it, resulting in the name Iron(III) Fluoride. The video concludes by explaining how to write the formula from the name.
