Copper Compounds and Ionic Bonds

The video tutorial explains how to write the formula for Copper(I) Nitrate. It begins by identifying copper on the periodic table and then looks up the nitrate ion, which is not on the periodic table but found in a table of common polyatomic ions. The nitrate ion is NO3 with a 1- charge. The tutorial explains that Copper(I) Nitrate is an ionic compound, consisting of a metal and nonmetals, and emphasizes the importance of balancing the charges to achieve a neutral compound. The copper ion has a 1+ charge, and the nitrate ion has a 1- charge, which together balance to zero. The final formula for Copper(I) Nitrate is CuNO3.
