No. of Ca+2 ions=4 No. of F- ions=8 one Ca ion combines with 2 Fe ions.
So, number of CaF2 ions=4.

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.
