Final answer:
The bond in Calcium fluoride, CaF₂, is an ionic bond formed through the transfer of electrons.
Step-by-step explanation:
The bond in Calcium fluoride, CaF₂, is an ionic bond.
An ionic bond is formed when there is a complete transfer of electrons from one atom to another.
In CaF₂, calcium (Ca) donates two electrons to fluorine (F), resulting in the formation of calcium ions (Ca⁺²) and fluoride ions (F⁻). The opposite charges of the ions attract each other, creating an ionic bond.
