Question

which image represents the ionic compound strontium fluoride, srf2? a. :f: - sr - :f: b. :f: - sr - :f: c. sr+2 2(:f:)-1

Explanation:

Ionic compounds are composed of ions. Strontium (\(Sr\)) has a +2 charge (\(Sr^{+2}\)) as it is in Group 2 of the periodic table and loses 2 electrons. Fluorine (\(F\)) has a -1 charge (\(F^{-}\)) as it is in Group 17 and gains 1 electron. In \(SrF_{2}\), there is one \(Sr^{+2}\) ion and two \(F^{-}\) ions. Option C shows \(Sr^{+2}\) and two \(F^{-}\) ions (represented as \(2[:\ddot{F}:]^{-1}\)), which is the correct ionic representation. Option A shows covalent - like bonding (represented by lines which are for covalent bonds, not ionic). Option B shows electron transfer (arrows) which is part of the formation process but not the final ionic compound structure.

Answer:

C. \(Sr^{+2}2[:\ddot{F}:]^{-1}\)
