State of matter - solid
Heavy metal-brittle
Discovered in 1879 by Lars Fredrick Nilson
Boils at 2832 °C, melts at 1539 °C
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.
