Understanding Nomenclature of Binary and Ternary Compounds
This guide delves into the nomenclature of binary and ternary compounds, including specific naming rules for compounds formed by metals with fixed and variable oxidation states, as well as nonmetals. It explains how to apply the Criss-Cross Rule for naming and provides examples such as sodium chloride and aluminum iodide. Additionally, it covers the naming of common cations and anions, giving clarity to the terminology utilized in chemical formulas. Essential for students and chemistry enthusiasts, this resource compiles critical concepts into a comprehensive overview.

Four Types of Naming • Binary compounds • Ternary compounds • Coordination compounds • Organic compounds Contain only two types of elements Contain more than two types of elements These will not be covered We will cover these in a separate unit
Binary Compounds Metals (fixed oxidation) + Nonmetals
Binary Compounds Binary compounds that contain a metal of fixed oxidation number (group 1, group 2, Al, Zn, Ag, etc.), and a non-metal. To name these compounds, give the name of metal followed by the name of the non-metal, with the ending replaced by the suffix –ide. Examples: NaCl sodium chloride (Na1+ Cl1-) CaS calcium sulfide (Ca2+ S2-) AlI3 aluminum iodide (Al3+ I1-)
