Naming and Identifying Ternary Compounds

Dr. B explains how to name the ternary ionic compound Ca(NO2)2. The video covers identifying the compound type, naming the metal calcium using the periodic table, and naming the polyatomic ion NO2 as nitrite using a common ion table. The video concludes with a representation of the compound using a Lewis structure and encourages further practice on the Naminator website.
