Atomic bit : 103Atomic symbolisation : LrAtomic Weight : 262Melting Point : 2,961 F ( 1,627 C)Boiling Point : Unknown
Word Origin : Lawrencium is key out for Ernest O. Lawrence , artificer of the cyclotron , which was subservient in the discovery of many elements .
Lawrencium
Discovery : Lawrencium was find at the University of California , Berkeley , by Albert Ghiorso , Torbjørn Sikkeland , Almon E. Larsh and Robert M. Latimer in 1961 .
Properties of Lr
Despite its placement late in theactinide serial publication , lawrencium behaves more like the tripositive elements that come earlier in the actinon series , and less like dipositivenobelium , its neighboring element . [ SeePeriodic board of the Elements ]

atomic number 103 is artificially produced , and has only been made in diminished quantity .
It can be produced by bombardingcaliforniumplaced in a linear accelerator withboronions . This method acting has been used in multiple experiments and several dissimilar isotopes of Lr have been produced this way .
atomic number 103 has 10 recognized isotopes . Its most stable is262Lr , with a half - life of about four hours .
use of goods and services of atomic number 103
Because atomic number 103 has only been produced in small quantity , its only use is for scientific research .
