Formula and Structure of Calcium Chloride. Calcium chloride is created from the ionic bonds that form between calcium cations and chloride anions. Calcium ions have a charge of +2, while chloride ions have a charge of -1. The molecule for calcium chloride has one calcium ion (+2) and two chloride ions (-1), which means that the overall charge for the molecule is 0, or neutral. On screen is the chemical reaction for the formation of calcium chloride.
