- Notes:
- Very few uses of this unusal metal have been discovered. Its low density and
- high melting point suggest applications as an alloying agent for devices
- requiring light-weight metals. It emits a stong gamma radition with an 85-day
- half-life. The chemistry of this element is similar to aluminium and titianum.
