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 chemical makeup of fluorite?
From a mineralogical perspective, fluorite is an evaporite mineral that contains one calcium ion and two fluorine ions. Calcium may also be substituted partially accounting for different colours of the mineral but it is usually purple.
Why does the ionic compound calcium fluoride have a different structure from that of calcium chloride?
Calcium fluoride has the fluorite structure where each calxium ion has 8 fluoride ions as near neighbours at the corners of a cube, and eacf fluoride has 4 calcium ions ate the corners of a tetrahedron. Another way of looking at this is that the calcium ions are close packed and the fluroide atoms fill the "tetrahedral holes" In calcium chloride the chloride ion is too large to allow eight coordination and the coordination around the calcium drops to 6, the coordination around the chloride has to drop to 3. This gives CaCl2 a unique structure which is a distorted form of the more regular rutile structure adopted by TiO2.
What is the mass of calcium fluoride?
The molecular mass of calcium fluoride is 78,07 g.
A sample of tap water consists of water fluoride ions calcium ions and several other dissolved ions The ions are evenly distributed throughout the water Which term or terms could be used to descr?
Homogenous. AkA solution.
Crystals of the ionic compound calcium fluoride have a different structure from that of the ionic compound calcium chloride?
The size of a chloride ion is much larger than the size of a fluoride ion. CaF2 arranges in the fluorite crystal structure , The holes where these fluoride ions fit in between the closely packed calcium cations are a certain size, which aren't big enough for chloride ions to fit into. Therefore, CaCl2 has to form a different crystal structure that allows for the larger anion size.
Why is calcium fluoride have a smaller boiling point then magnesium fluoride?
The calcium ion is larger than the magnesium ion and so the charge on it is less dense. This makes it less attracted to the fluoride ions
Explain what the formula CaF2 tells you about this compound?
Ca+2 F-1 <----- these are the ions and their charges Ca+2 F-1 F-1 <----- the charges have to add up to zero, so two -1 fluorine ions cancel out one +2 calcium ions CaF2 <---- simplify

Is Fluoride ions a mixture?
Fluoride ions (F-), being a charge species, cannot exist on their own. The same is true of all ions. They must be accompanied by a positive ion (such as Na+ or Ca2+) to balance their negative charge. The substances collectively referred to as fluorides (sodium fluoride, calcium fluoride, etc.) are compounds.

Yes

Is calcium fluoride flammable?
No. Calcium fluoride is not flammable.
