Identify the element of the cation and anion as a metal or nonmetal. Determine the charge of the cation by balancing the charge of the anion. The cation is named by its element name. If the metal shows variable charge, include the Roman numeral to indicate the charge in parentheses. The anion is named by adding ide to the first syllable of the name of its element.

The element in anion is chlorine $\left(\mathrm{Cl}\right)$, a nonmetal in Group 7A and forms anion with one negative charge $\left({\mathrm{Cl}}^{-}\right)$. Name the anion as oxide by adding ide to chlor, first syllable of the lame of chlorine

There are two chloride anions with a total of two negative charge and one cation. To counter valance, the charge on cation must be two positive.

Name the cation as tin by its element name and include (II) to indicate the charge as tin can form cations with variable charge. Thus, the name of cation is tin(II) and the name of the ionic compound is tin(II) chloride.
