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.

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 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 has the chemical formula CaF2, where there is one calcium atom and two fluorine atoms bonded together. Aluminum sulfide has the chemical formula Al2S3, where there are two aluminum atoms and three sulfur atoms bonded together.


What is the oxidation number of calcium (Ca) in CaF2?

The oxidation number of calcium (Ca) in CaF2 is +2. This is because fluorine (F) typically has an oxidation number of -1, and the overall charge of CaF2 is neutral. Since there are two fluorine atoms each with a -1 charge, the calcium atom must have a +2 oxidation number to balance the charges.


How many grams of f are in 165 caf2 grams of?

To find the grams of F in 165 g of CaF2, you need to consider the molar mass of CaF2. Calcium (Ca) has a molar mass of about 40.1 g/mol, and fluorine (F) has a molar mass of about 19 g/mol. So, the molar mass of CaF2 is about 40.1 + (19 x 2) = 78.1 g/mol. Then, you can calculate the grams of F in 165 g of CaF2 by determining the proportion of F in the compound CaF2 compared to its total molar mass.

How many atoms are present in 7.92g of calcium fluoride?

Calculate the number of moles of calcium fluoride by dividing the mass by its molar mass. The molar mass of calcium fluoride (CaF2) is 78.08 g/mol. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms present in 7.92g of calcium fluoride.
