Question

the ionic compound pb(no₃)₂ is used in the manufacture of matches. what is its name? refer to a periodic table and a list of polyatomic ions. its name is

Explanation:

Lead can form ions with different charges. The nitrate ion ($\ce{NO_{3}^{-}}$) has a charge of -1. In $\ce{Pb(NO_{3})_{2}}$, since there are two nitrate ions (total charge from nitrate is - 2), the lead ion must have a charge of +2. The naming convention for ionic compounds with metals that have variable charges uses Roman numerals to indicate the charge of the metal ion.

Answer:

Lead(II) nitrate
