The reason it becomes stable is because Ca has 2 valence electrons that it wants to get rid of to become stable. F has 7 valence electrons and wants 1 more to become stable. So, TWO F atoms each take 1 of the 2 electrons from Ca. They form an ionic bond as Ca^2+ and 2F^- to make CaF2.

How many fluorine atoms bond to calcium to form calcium fluoride?
In calcium fluoride, one calcium atom bonds with two fluorine atoms to form a stable ionic compound.
What is the valency of fluorine in calcium fluoride?
The valency of fluorine in calcium fluoride is -1. Calcium has a valency of +2, so the formula for calcium fluoride is CaF2. Each calcium atom donates two electrons to each fluorine atom, resulting in a stable ionic compound.
What are the ions for calcium fluoride?
The individual ions for calcium fluoride have the formulas Ca+2 and F-1 respectively. That means that in any sample of calcium fluoride, there must be twice as many of the fluoride ions.
What is the mass of calcium fluoride?
The molar mass of calcium fluoride (CaF2) is approximately 78.08 g/mol.
What is the name of the compound ionic bond of calcium and fluorine?
The compound formed from the ionic bond between calcium and fluorine is called calcium fluoride (CaF2).
