CaF2
CaF2, Calcium Fluoride. It is useful in iron smelting
Two fluorine atoms. the formula of calcium fluoride is CaF2.
two
Calcium sulfate (CaSO4) is a compound.
clf
Calcium fluoride.
Calcium and fluorine
The Pauling electronegativity of calcium is 1,00.The Pauling electronegativity of fluorine is 3,98.
CaF2
The formula CaF as written in the question shows two atoms; however this formula does not represent any actual compound. The compound between calcium and fluorine has the formula CaF2, because calcium forms divalent cations and fluorine forms monovalent anions. Therefore, the formula unit for calcium fluoride contains 3 atoms.

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
CaF2
Ionic
Calcium is a group 2 metal, with the symbol Ca, whereas fluorine is a halogen (group 7) and goes around in pairs (Fl2)
Fluorine is more electronegative than calcium. The electronegativity of calcium is 1. The electronegativity of fluorine is 3.98.
Calcium reacts with fluorine to form calcium fluoride (the symbol is CaF2).
