Radium is a radio active element which always undergoes nuclear fission and desentegration, and releases energy in the form of radiation. It is an element. There is no compound in it. It contains atoms of radium.
Radium is a divalent chemical element; the cation is Ra2+.
sulfur
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
The chemical formula of radium sulphate will be RaSO4, but this compound is not still prepared.
