Ions and Isotopes Concepts

This video tutorial from Moomoomath and Science covers isotope and ion notation. It explains isotopes as elements with differing numbers of protons and neutrons, using carbon as an example. The video details how to write isotope notation and introduces ions, which are elements with a charge. It explains the difference between cations and anions and provides rules for naming them. The tutorial concludes with a brief mention of transition metals and encourages viewers to subscribe for more content.
