Answer 1

In the formation of calcium fluoride, each calcium atom transfers one electron to each of two fluorine atoms, forming a Ca2+ ion and two F- ions, which then combine to form CaF2.

Step-by-step explanation:

The formation of calcium fluoride (CaF2) from elemental calcium (Ca) and elemental fluorine (F2) involves a transfer of electrons between the atoms. Each calcium atom has two valence electrons, and each fluorine atom needs one electron to complete its octet and achieve a stable electronic configuration.

The electron transfer occurs as follows: each Ca atom transfers one electron to each of two fluorine atoms. This results in the formation of a Ca2+ ion, as it loses two electrons, and two F- ions since each fluorine atom gains one electron. The process of electron transfer ensures that the number of electrons lost by calcium is equal to the number of electrons gained by the fluorine atoms.

After the transfer, the oppositely charged ions attract each other and form an ionic bond, resulting in the ionic compound calcium fluoride with the formula CaF2.
