(a)
Interpretation: The ions required to form calcium fluoride needs to be determined.
Concept Introduction: An ionic compound is formed when a metal reacts with a non-metal. Here, metal is electron efficient and loses electrons while non-metal is electron deficient, thus, it gains electrons. In an ionic compound, metal has a positive charge and non-metal has a negative charge.
