Lead Nitrate and Polyatomic Ions

The video tutorial explains how to name the compound Pb(NO3)2. It begins by identifying the nitrate ion as a polyatomic ion and recognizing lead as a transition metal. The tutorial then details the process of naming the compound by first naming the lead and nitrate ions. It further explains how to determine the charge of lead, given its bonding with two nitrate ions, and concludes with the complete name: lead(II) nitrate.
