Question

which image depicts the transfer of electrons between strontium and fluorine when they form an ionic compound? a. :f - sr - f: b. :f. ← sr →.f: c. sr+2 2:f:^-1

Explanation:

Strontium (Sr) is a metal in Group 2, it loses 2 electrons to form a +2 ion. Fluorine (F) is a non - metal in Group 17, it gains 1 electron to form a - 1 ion. In an ionic compound of Sr and F, Sr gives 2 electrons to 2 F atoms. Option C shows the correct ionic form with Sr²⁺ and two F⁻ ions. Option A shows covalent - like bonding, and option B shows an incorrect electron - transfer representation.

Answer:

C. Sr⁺² 2[:F:]⁻¹
