Explanation:

• For ionic compounds with transition metals (like Pb - lead, which is a transition metal), we need to indicate the charge of the metal ion using Roman numerals.
• The carbonate ion is \(CO_{3}^{2 -}\). In \(PbCO_{3}\), since the carbonate ion has a charge of \(- 2\), the lead ion (\(Pb\)) must have a charge of \(+ 2\) to balance the charge in the neutral compound (\(+2+( - 2)=0\)).

Answer:

Lead (II) carbonate
