Once this goes to GA, we'll have an actinide GT. Parcly Taxel 09:53, 9 September 2014 (UTC)

7. Overall:

   Pass or Fail:

Lead

• "Twelve isotopes of lawrencium are currently known: the most stable is ²⁶⁶Lr with a half-life of 11 hours; but the shorter-lived ²⁶⁰Lr (half-life 2.7 minutes) is most commonly used in chemistry because it can be produced on a larger scale." Colon should be a semicolon, semicolon should be a comma.

History

• "Eighteen tracks were noted, with decay energy around (9 ± 1) MeV and half-life around 1⁄4 s; the Berkeley team noted that while the cause could be the production of an isotope of element 103, other possibilities could not be ruled out."

Characteristics -> Chemical

• "It has been speculated that the 7s electrons would be are relativistically stabilized, so that in reducing conditions, only the 7p_1/2 or 6d electron would be ionized, leading to the monovalent Lr⁺ ion."

Atomic

• "If the s²p configuration is correct, then lawrencium could not cannot be regarded as a transition metal under the IUPAC definition ("An element whose atom has an incomplete d sub-shell, or which can give rise to cations with an incomplete d sub-shell."), …"
