Properties and Naming of Mn2O3

The video tutorial explains how to name the compound Mn2O3. It starts by identifying Mn2O3 as an ionic compound composed of a metal (manganese) and a non-metal (oxygen). 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 further explains the significance of manganese being a transition metal, which can have multiple charges. The tutorial calculates the ionic charges, ensuring the net charge is zero, and concludes by naming the compound manganese(III) oxide, indicating the charge of manganese with a Roman numeral.
