Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4). These compounds are generally highly radioactive due to the nature of radium as a radioactive element.
