Element Lawrencium (Lr), Group 20, Atomic Number 103, f-block, Mass [262]. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
A radioactive metal, lawrencium is the eleventh transuranium element, the third transfermium, and the last member of the actinide series. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles.
The key properties of lawrencium are listed below: It is a synthetic, highly radioactive metal; It has a short half-life; It exists as a trivalent ion in aqueous solution. Applications. Other than scientific research, lawrencium has no specific applications currently. References. http://www.webelements.com/lawrencium/
Definition, mass & chemical names. Lawrencium is a synthetic element and is highly radioactive and unstable element. It is the last member of the actinide series of the periodic table. History and Discovery.
Dubna, Russia (Figure 4.103.1). The element is named for Ernest O. Lawrence (Figure 4.103.2), who developed the cyclotron. The chemical symbol for lawrencium was originally proposed as Lw. At the IUPAC General Assembly in 1963, lawrencium was officially accepted by IUPAC,
30 Ιουν 2023 · Chemistry of Lawrencium. The last of the actinide metals and only the second of the transuranium elements that Glenn Seaborg was not involved with, element 103 was synthesized in 1961 by Ghiorso, Sikkeland, Larsh and Latimer at the Lawrence Radiation Laboratory (and named for Ernest Lawrence, the inventor of the cyclotron).
Download reference work entry PDF. Lawrencium (Lr), atomic number (Z) 103, is the fourteenth, and final, member of the actinide series. Ten isotopes (mass = 252–262) have been synthesized and observed. Lawrencium has no natural abundance; the half-lives range from 0.6 s to 216 min.
