Lawrencium:

The first type of particle accelerator, the cyclotron, invented by Ernest Lawrence, was used to synthesize many new elements.

Facts about Lawrencium:

  • Lawrencium: Lawrencium is a synthetic element, and is expected to have similar properties to Lutetium which sits just above it in the periodic table.
  • Fun fact about Lawrencium: Lawrencium is expected to be a very heavy metal, with a melting point around 1900 K - or over 2000 deg.C!
  • Chemical symbol: Lr
  • Atomic number: 103

A crystal structure celebrating Lawrencium:

In part of this crystal structure, a special molecular cage made of carbon (grey sticks) known as a fullerene is used to trap atoms of lutetium (green balls).

Facts about this structure:

  • Formula: C76 6-,2(C6 H6),2(Lu 3+),C36 H44 N4 Ni
  • Structure name: di-lutetium (Td)-C76fullerene-hexaide (2,3,7,8,12,13,17,18-octaethylporphyrinato)-nickel(ii) benzene solvate
  • Fun fact about the structure: Fullerenes have been used to isolate many different elements.  Perhaps someday scientists will be able to trap Lawrencium in this way.

More info:

Lawrencium is named for physicist Ernest O. Lawrence who invented the cyclotron, which is a type of particle accelerator.  Modern-day particle accelerators are used to create new elements, such as Lawrencium, by smashing smaller atoms and particles together.  Truly, this science has come full-circle.
