Naming and Properties of FeF3

The video tutorial explains how to name the compound FeF3. It starts by identifying FeF3 as a binary ionic compound composed of a metal (iron) and a non-metal (fluorine). The tutorial details the process of naming the metal and non-metal according to the periodic table, replacing the non-metal's ending with 'ide'. It then discusses the importance of determining the ionic charge of the transition metal iron, which is bonded to three fluorine atoms, each with a 1- charge. This results in iron having a 3+ charge, leading to the name iron(III) fluoride. The video also mentions the older name, ferric fluoride.
