The formula of calcium fluoride is $C a F_{2}$ $CaF_2$ .

Explanation:

Calcium, a Group 2 metal, commonly forms a $C a^{2 +}$ $Ca^(2+)$ ion. On the other hand, fluorine, a Group 7 non-metal, commonly forms an $F^{-}$ $F^-$ ion. The necessity of electrical neutrality ensures that $2 \times F^{-}$ $2xxF^-$ binds to one $C a^{2 +}$ $Ca^(2+)$ .

Note that the structure of the mineral, fluorite, affords very high physical constants as it is a very stable structure. $L i_{2} O$ $Li_2O$ is called $antfluorite$ $"antfluorite"$ . Why?
