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 is called calcium fluoride. It occurs naturally as a mineral called Fluorite (also called fluorspar).
The compound of CaF2 is known as Calcium fluoride. Each molecule contains one calcium atom and 2 fluorine atoms. It is soluble in water.
F- Fluorine
Ca- Calcium
CaF2 - Calcium fluoride
Calcium fluoride is an inorganic compound (salt), ionic.
CaF2 is the chemical formula of calcium fluoride.
This compound (calcium fluoride) is formed from calcium and fluorine.
Calcium Fluoride
CaF2
Formula: CaF2
CaF2.
Calcium fluoride is a binary compound.
You think probable to calcium difluoride CaF2.
The correct formula is CaF2. It is calcium fluoride.
CaF2
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+.
CaF2
CaF2
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.
CaF2 is calcium fluoride.
