Answer:
Explanation:
Calcium is the element of the group 2 and period 4 which means that the valence electronic configuration is ![[Ar]4s^2](https://tex.z-dn.net/?f=%5BAr%5D4s%5E2)
.
Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is ![[Ne]3s^23p^5](https://tex.z-dn.net/?f=%5BNe%5D3s%5E23p%5E5)
.
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,
Thus, the formula of calcium chloride is .
