Question

Show the formation of CaS by the transfer of electrons.

Answer 1

Answer:

By transfer of electrons between Calcium and sulfide ions the compound Calcium sulfide can be formed.

Explanation:

Calcium has an electronic configuration $2,8,8,2$. It has $2$ valence electrons and to attain a stable electronic configuration it has to lose those two electrons and becomes a calcium ion.

$Ca \rightarrow Ca^{2+}+2e^-$

Sulfur has an electronic configuration $2,8,6$. To achieve a stable configuration it must gain two more electrons. Once gained electrons it becomes a sulfide ion.

$S+2e^- \rightarrow S^{2-}$

By combining both ions by transferring electrons, the compound $CaS$ may be formed.

$Ca^{2+} + S^{2-} \rightarrow CaS$
