lawrencium
n 1: a radioactive transuranic element synthesized from
californium [synonym: {lawrencium}, {Lr}, {atomic number 103}]

lawrencium \lawrencium\ n. [from Ernest O. Lawrence, inventer of
the cyclotron.]
A transuranic element of atomic number 103. It was discovered
in 1961 by bombardment of californium in a cyclotron with
boron nuclei. Other isotopes were prepared in 1965 at Dubna.
The atomic weight of the most stable isotope is 256, having a
half-life of 35 seconds. Symbol Lr. --HCP61

Syn: Lr.
[WordNet 1.5]


Lr \Lr\ n.
The chemical symbol for {lawrencium}, a transuranic element
of atomic number 103.
