Question

if the metal in the ionic compound is a transition elemer
name the ionic compound pbcl₄.
spell out the full name of the ionic compound.

Explanation:

Pb is lead. In ionic compounds with transition metals, the charge of the metal is indicated by a Roman numeral. Chloride has a charge of -1. For \(PbCl_4\), since there are 4 chloride ions (\(Cl^-\)), the lead ion (\(Pb^{n+}\)) must have a charge of +4 to balance the charges (\(n + 4\times(-1)=0\), so \(n = 4\)).

Answer:

Lead(IV) chloride
