Step 1: Understand the problem
We are given an ionic compound, PbS₂, and we need to find the ionic charge of lead (Pb).
Step 2: Recall the rules of ionic compounds
In an ionic compound, the overall charge must be zero. This means that the sum of the charges of all the ions must equal zero. Additionally, the charge on an ion is equal to its group number in the periodic table. For transition metals, however, the charge can be determined by the oxidation state. In this case, lead is in group 14, but it has a charge of + 2 in its most common oxidation state.
Final Answer
In the corrected compound PbS, the ionic charge of lead is + 2.
