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

#### Explanation:

$C a {F}_{2}$ is conceived to be formed of 2 ions, $C {a}^{2 +}$, 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.
