Naming and Charging Monoatomic Ions

Dr. Kent introduces monoatomic ions, explaining that they consist of a single atom. The video covers how non-metals gain electrons to form anions and how metals lose electrons to form cations. The concept of the Magic Triangle is introduced to explain fixed charges in certain metals, while other metals have variable charges. The video also details the naming conventions for ions, including the use of Roman numerals for variable charge metals. Several examples are provided to reinforce the concepts discussed.
