Naming and Charges of Copper Compounds

The video tutorial explains how to name the compound Cu(NO3)2. It begins by identifying the components: copper, a transition metal, and nitrate, a polyatomic ion. The tutorial then outlines the steps to name the compound, starting with the metal followed by the polyatomic ion. Since copper is a transition metal, its charge must be determined based on the nitrate ions it bonds with. The nitrate ion has a charge of 1-, and with two nitrate ions, the total negative charge is 2-. Therefore, copper must have a charge of 2+, leading to the name Copper(II) Nitrate.
