Answer:
Calcium and Chlorine form ionic compound.
Explanation:
Ionic compounds are formed when there is a transfer of electrons from the metallic atom to the non-metallic atom. Ionic compounds can only be formed between a metal and a non metal.
Calcium is the metal and chlorine is the non-metal. Calcium will form ionic bond with chlorine by transferring two electrons to the chlorine atom to become calcium ion(Ca^2+) and the chlorine atom becomes chloride ion (Cl^-). This can be illustrated in the equation below
1. Ca —> Ca^2+ + 2e^-
2. Cl2 + 2e^- —> Cl2^-
Combining 1 and 2
Ca +Cl2 +2e^- —>Ca^2+ + Cl2^- + 2e^-
The electrons will cancel out, forming
Ca + Cl2 —> Ca^2+Cl2^- (ionic compounds)
