CHEMICAL AND PHYSICAL PROPERTIES
| Color/Form | Brilliant white metal; body-centered cubic structure. /Radium metal/ |
|---|---|
| Boiling Point | 1737 °C /Radium metal/ |
| Melting Point | 700 °C /Radium metal/ |
| Density | 5.5 g/cu cm /Radium metal/ |
| Stability/Shelf Life | Blackens on exposure to air; ...undergoes spontaneous disintegration with formation of radon |
| Other Experimental Properties | Pure metal is brilliant white when freshly prepared; blackens on exposure to air, probably due to formation of nitride; atomic number 88; valance 2+; decomposes in water. |
