Assuming it is Pb(NO3)2, in this case, in order to name this compound, we need to know what each element are named separately, this is usually 90% of the work when we have to name compounds. Pb is the element Lead, and NO3 is the nitrogen oxoanion Nitrate, now because Pb is a transition metal, it has a few possible oxidation numbers (the charge when it bonds with another element), and because of these multiple possibilities, we need to identify the charge of Pb when we name it, since we have NO3, and nitrate has a charge of -1, and we have 2 Nitrates, the charge of Pb, in order to counterbalance it, is +2, now, naming the compound, we will have:
Lead (II) nitrate
The bond type it will be an Ionic bond, since we have different charges
