What type of bond is CaSO4?

Calcium sulfate (CaSO4) is primarily held together by ionic bonds. In this compound, calcium (Ca²⁺) donates two electrons to sulfate (SO4²⁻), resulting in the formation of ionic bonds between the positively charged calcium ions and the negatively charged sulfate ions. This ionic nature gives CaSO4 its characteristic properties, such as high melting point and solubility behavior.
