Question

name snf₂ by the stock (iupac) system.

Explanation:

The Stock (IUPAC) system names ionic compounds. Sn (tin) is a metal with variable oxidation states. Fluoride (\(F^-\)) has a -1 charge. In \(SnF_2\), there are two \(F^-\) ions, so the tin ion must have a +2 charge. In the Stock system, we use Roman numerals to indicate the oxidation state of the metal.

Answer:

Tin(II) fluoride
