The balanced equation for the reaction between calcium and chlorine is: $Ca(s)$ $"Ca(s)"$ + ${Cl}_{2} (g)$ $"Cl"_2"(g)"$ $\to$ $rarr$ ${CaCl}_{2}$ $"CaCl"_2$ . During this reaction, the calcium atom gives its two valence electrons to two chlorine atoms. Each chlorine atom initially has seven valence electrons.This causes the calcium atom to become a cation with a 2+ charge, and each chlorine atom to become an anion with a 1- charge. The oppositely charged ions form an electrostatic attraction, which is an ionic bond. This process can be represented in a chemical equation as follows:

$Ca(s)$ $"Ca(s)"$ + ${Cl}_{2} (g)$ $"Cl"_2"(g)"$ $\to$ $rarr$ ${Ca}^{2 +}$ $"Ca"^(2+)$ + ${Cl}^{-}$ $"Cl"^(-)$ + ${Cl}^{-}$ $"Cl"^(-)$ $\to$ $rarr$ ${CaCl}_{2}$ $"CaCl"_2$

The following diagram uses Lewis dot structures to demonstrate the formation of calcium chloride.
