Calcium fluoride or CaF2 is comprised of two elements: calcium (Ca) and fluoride (F). One molecule of CaF2 thus contains two atoms of F and one of Ca for a total of three.

In one molecule, calcium fluoride has:
1 calcium atom
2 fluorine atoms
3 atoms total
Because there is a three in the front of the formula, it means there are three of those molecules. So if one molecule has 3 atoms, 3 molecules will have 9 atoms total.

How many atoms are present in 7.92g of calcium fluoride?
7.92 grams calcium fluoride (1 mole CaF2/78.08 grams)(6.022 X 1023/1 mole CaF2) = 6.11 X 1022 atoms of calcium fluoride --------------------------------------------------
How many atoms are in calcium bromide?
The chemical formula for zinc floride is ZnF2. Thus, a single molecule of zinc floride contains one zinc atom and two floride atoms, for a total of three atoms.
How many fluorine atoms bond to calcium to form calcium fluoride?
Two fluorine atoms. the formula of calcium fluoride is CaF2.
What is the formula of calcium fluoride?
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.
What is the molar mass of calcium fluoride?
The formula is CaF2 so, its three atoms, one calcium and two fluorine atoms. add the molar mass of calcium(40 g/mol) and fluorine(19 g/mol X 2 because there are two atoms of fluorine) and you get 40+(19x2)=78 78 grams per mol
Write formulas for a compound with one calcium atom and two fluorine atoms and for a compound with two aluminum atoms and three sulfur atoms?
Calcium difluoride, CaF2 Dialuminium trisulphide, Al2S3
How many atoms are present in 7.92g of calcium fluoride?
7.92 grams calcium fluoride (1 mole CaF2/78.08 grams)(6.022 X 1023/1 mole CaF2) = 6.11 X 1022 atoms of calcium fluoride --------------------------------------------------
How many atoms are in calcium bromide?
The chemical formula for zinc floride is ZnF2. Thus, a single molecule of zinc floride contains one zinc atom and two floride atoms, for a total of three atoms.
Identify the correct formula for a compound with one calcium atom and two fluorine atoms?
CaF2
What is the mass of 0.06 mole of CaF2?
1 mole CaF2 = 78.074g CaF2 0.06mol CaF2 x 78.074g CaF2/mol CaF2 = 5g CaF2 (rounded to 1 significant figure)
How many fluorine atoms bond to calcium to form calcium fluoride?
Two fluorine atoms. the formula of calcium fluoride is CaF2.
How many moles are in 58.2 grams of calcium fluoride?
The formula mass of CaF2 is 40.1 + 2(19.0) = 78.1 Amount of CaF2 = 58.2/78.1 = 0.745mol
What are formulas for a compound with one calcium atom and two fluorine atoms and a compound with two aluminum atoms and three sulfur atoms?
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
What is the formula of calcium fluoride?
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.
What is the name for the ionic compound caf2?
CaF2 is calcium fluoride.
What has an enthalpy change that is numerically opposite to the lattice energy of CaF2?
Of these choices:a. Ca(s) + F2(g) → CaF2(s)b. Ca(g) + F2(g) → CaF2(s)c. Ca2+(g) + 2F−(g) → CaF2(s)d. Ca(g) + 2F(g) → CaF2(s)
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
