Final answer:
The compound CaCl₂ is made up of calcium ions (Ca2+) and chloride ions (Cl-).
Step-by-step explanation:
The compound CaCl₂ is made up of calcium ions (Ca2+) and chloride ions (Cl-). Calcium donates two electrons to each chlorine ion, creating Ca2+ and two Cl- ions. The oppositely charged ions attract each other to form CaCl₂.
