Calcium and chlorine form CaCl₂ rather than CaCl because less energy is required to remove one electron from the calcium atom than to remove two electrons more energy is released in forming chloride ions from chlorine molecules in the formation of CaCL(s) the lattice energy of CaCl (s) is less exothermic than of CaCl₂ (s) CaCl (s) is formed its elements, more energy is released than when CaCl₂ (s) is formed from its elements
