Radium nitrate is a radioactive salt with the formula Ra(NO₃)₂. It is a white solid, but old samples appear yellowish-grey. Although radium chloride and radium bromide are less soluble than the corresponding barium salts, radium nitrate is more soluble than barium nitrate.^[1]^[2] It decomposes at 280 °C to radium oxide.^{[citation needed]}
