Heavy metal-brittle
Discovered in 1879 by Lars Fredrick Nilson
Boils at 2832 .C, melts at 1539 .C

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.
