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:

Step1: Recall ionic - compound structure

Ionic compounds consist of ions. Strontium ($Sr$) is a metal and forms a $Sr^{2 + }$ ion, and fluorine ($F$) is a non - metal and forms $F^{-}$ ions.

Step2: Analyze each option

Option A shows covalent - like bonding with lines between atoms, which is incorrect for an ionic compound. Option B also shows some form of electron - sharing or transfer in a non - ionic way. Option C correctly shows the $Sr^{2+}$ ion and two $F^{-}$ ions, which is the correct representation of the ionic compound $SrF_{2}$.

Answer:

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