| Molecular Structure: |  |
| Properties | |
| Transport: | 3321 |
| Melting Point: | -71 deg C |
| Boiling Point: | -61.7 deg C (liquid) |
| Solubility: | In water, 230 cu cm/L at 20 deg C Soluble in organic solvents Fairly soluble in water - 51.0 cu cm radon/100 cu cm water at 0 deg C; 22.4 cu cm radon/100 cu cm water at 25 deg C; 13.0 cu cm radon/100 cu cm water at 50 deg C |
| Color: | Colorless gas Can be condensed to a colorless, transparent liquid & to an opaque, glowing solid. When cooled below the freezing point, radon exhibits a brilliant phosphorescence which becomes yellow as the temperature is lowered and orange-red at the temperature of liquid air. Solid form exists as face-centered cubic crystals at normal pressure. |
