Answer:

$CaCl_2$

Explanation:

Calcium is the element of the group 2 and period 4 which means that the valence electronic configuration is $[Ar]4s^2$ .

Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is $[Ne]3s^23p^5$ .

Thus, calcium losses 2 electrons to 2 atoms of chlorine and these 2 atoms of chlorine accepts each electron to form ionic bond. This is done in order that the octet of the atoms are complete and they become stable.

Ca Cl

2 1

Cross multiplying the valency, We get, $CaCl_2$

Thus, the formula of calcium chloride is $CaCl_2$ .
