WebApr 9, 2024 · CaF2 is an ionic compound because, in the CaF2 molecule, calcium acts as a cation by donating its 2 extra electrons from the valence shell, and Fluoride acts as an anion by accepting the electrons from Calcium, completing its octet. Therefore, Calcium and fluoride together form an ionic bond, i.e., CaF2. The bond angle between CaF2 is 154 ... WebThe mineral CaF2 has a solubility of 2.1 x 10^-4 M.
