Chemistry Properties and Structure of Matter: Properties of Matter - Naming Monoatomic Ions

This video tutorial introduces chemical nomenclature, focusing on writing chemical formulae and naming monoatomic ions. It defines key terms like compounds, cations, anions, and the role of IUPAC. The lesson distinguishes between organic and inorganic compounds and explains how to write chemical formulae for ions. It also covers oxidation states and naming conventions for ions, emphasizing the importance of standardized nomenclature for clear communication in chemistry.
