Question

In calcium fluoride, ___________ bond formation takes place between calcium and fluorine.

Answer 1

Calcium fluoride($Ca{F}_2$) is an ionic molecule and the Ca loses $2$ valence electrons and forms $C{a}^{+2}$ and F gains an electron and forms $F^{-}$.

Between $C{a}^{+2}$ and $2F^{-}$ ions, an ionic bond is formed.

Hence, ionic bond is present in $Ca{F}_2$ molecule.
