	lawrencium - HighBeam Encyclopedia
		Lawrencium is the last member of the actinide series of elements found in Group 3 of the periodic table.
		Lawrencium was the 11th transuranium element to be discovered.
		It was first prepared in 1961 (after three years of preliminary work) by Albert Ghiorso, Torbjørn Sikkeland, Almon E. Larsh, and Robert M. Latimer at the Univ. of California at Berkeley; a sample of californium isotopes was bombarded with a beam of boron nuclei from the heavy-ion linear accelerator.

		Lawrencium (IPA: /ləˈrɛnsiəm/), also called eka-lutetium, is a radioactive synthetic element in the periodic table that has the symbol Lr and atomic number 103.
		Lawrencium is synthesized from californium and has no known uses.
		Lawrencium was discovered by Albert Ghiorso, Torbjørn Sikkeland, Almon Larsh and Robert M. Latimer on February 14, 1961 at the Berkeley Radiation Laboratory (now called Lawrence Berkeley National Laboratory) on the University of California, Berkeley campus.

	Lawrencium Summary
		The discovery of lawrencium was a result of a concerted effort by scientists to produce a new element.
		Lawrencium (Unniltrium, Unt, eka-Lutetium) is a radioactive synthetic element in the periodic table that has the symbol Lr and atomic number 103.
		Element 103 is a d-block element analogous to lutetium and therefore is increasingly being placed with the other d-block elements in the transition metal chemical series, but it is still most often grouped with the actinides in the periodic table.

		Lawrencium was discovered in March 1961 by A. Ghiorso, T. Sikkeland, A.E. Larsh, and R.M. Latimer.
		Lawrencium is a synthetic "rare earth metal" which does not occur in the environment.
		The electrically charged transmutation nuclei recoiled with an atmosphere of helium and were collected on a thin copper conveyor tape which was then moved to pace collected atoms in front of a series of soled-state detectors.

		Before enumerating Lawrence's many accomplishments, it is worth noting that lawrencium was created in 1961 by Albert Ghiorso, Torbjørn Sikkeland, Almon E. Larsh, and Robert M. Latimer at the University of California, Berkeley.
		His motives for promoting scientific achievement were selfless: Even though he patented the cyclotron, he rejected royalties and helped other labs to build their own cyclotrons, believing that "patent consciousness" would serve as a padlock on the doors of progress.
		While it may not have the easy recognition of oxygen or carbon, or the cachet of gold or platinum, lawrencium's history and status are beyond question.

		Lawrencium was created by four American scientists, Albert Ghiorso, Torbjørn Sikkeland, Almon E. Larsh and Robert M. Latimer, in March, 1961.

		Lawrencium is the second transferium element with the most stable isotope 262 Lr having a half-life of 216 minutes.
		It's chemical data are limited to its atomic number, its haf life and isotopes.
		Lawrencium doesn’t occur naturally, it has not yet been found in the earth’s crust and it’s so unstable that any amount formed would decompose to other elements very quickly.
