Question

During her presentation, Zahara was asked several questions from the audience and to provide the molecular formula for molecules that the audience had questions about. Show Zahara how to name Type 2 ionic compounds.Pb2S3

Answer 1

Explanation:

The following steps will guide us in naming an ionic compound

1. Determine the charge of the cation

2. Put roman numeral after the element name for the cation

3. The cation should come first and the anion should come second when naming

`\begin{gathered} Pb_2S_3 \\ \text{The cation is Pb and the anion is S} \\ \text{The valency electron of Pb is 2} \\ \text{Hence,} \\ Pb^{3+_{}}_2+S^(2-)_3\text{ }\rightarrow Pb_2S_3 \\ \text{Lead (III) sulfide} \end{gathered}`
