For example, the calcium atom in calcium chloride, CaCl 2, has two valence electrons, and the chlorine atoms have seven valence electrons each. Since bonding involves the valance shell electrons only, it is only necessary to illustrate those outer electrons. DTXSID60894886. Calcium, because it is an alkaline earth metal in period 4. Lewis dot diagram for calcium. Well, I couldn't find an actual picture, but I believe the lewis structure is Si=Ca=Si, based on Ca having 2 valence electrons and Si having 4 each. 4 answers.
