Its net charge is NEUTRAL, as is the net charge of all matter to a first approx.


#CaF_2# is conceived to be formed of 2 ions, #Ca^(2+)#, and #F^-#. Clearly, there must be 2 negative ions to balance the 2 positive charges of the metal ion.

The mineral itself, fluorite, is prized for its optical properties, and exhibits very low solubility in water on the basis of its structure.
