Question

Show on a diagram the transfer of electrons between the atoms in the formation of CaF2.
Please don't waste answers and answer fast I have test​

Answer 1

In CaF2, the number of electrons transferred from calcium to fluorine atom are 2.

Explanation:

CaF2 is a compound of Calcium and Flourine. The valency of Ca is +2. So, the calcium atom will donate two electrons to Flourine. Fluorine will thus reach the stable octet structure on its outer shell and form the CaF2 compound. Therefore, the number of electrons transferred from Ca to F in CaF2 are 2, one electron to each Fluorine atom.

Please see the diagram attached. The two red dots represent the electrons transferred from Ca to each F atom.
