CaF2 Calcium fluoride
CaF2
Fluorine, the element has a symbol/"formula" F. As a charged ion it has a -1 charge = F- Otherwise, fluorine is a diatomic molecule= F2 Calcium is also an element with symbol/"formula" Ca. As an ion it has a +2 charge, so it can be written as Ca2+.
The formula is:K(sp) = [Ca] . [F]2
165 degrees Celsius = 329 degrees Fahrenheit
There are 284.7 grams of F.
Calcium fluoride, CaF2
CaF2, Calcium Fluoride. It is useful in iron smelting
The correct formula is CaF2. It is calcium fluoride.
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
165 degrees Fahrenheit = 73.89 degrees Celsius
CaF2 Calcium fluoride

Fluorine, the element has a symbol/"formula" F. As a charged ion it has a -1 charge = F- Otherwise, fluorine is a diatomic molecule= F2 Calcium is also an element with symbol/"formula" Ca. As an ion it has a +2 charge, so it can be written as Ca2+.
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.
The formula is:K(sp) = [Ca] . [F]2
Ca 2+ and F - Bond together to form CaF2 Which is Calcium fluoride -----------------------
