The text of the entry was: Did you know ... that the discoverers of mendelevium had to seek the permission of the United States government to propose it be named after Russian chemist Dmitri Mendeleev, father of the periodic table?

We can mine this article by one of the codiscoverers of Md. After that everything is done, we can get GA, and we can move on to the next actinide: nobelium. Double sharp (talk) 14:38, 6 August 2014 (UTC)
"…with a half-life of 51 days:; nevertheless, the shorter-lived…" (semicolon, not colon)
"It was first synthesized by Albert Ghiorso, Glenn T. Seaborg, Gregory R. Choppin, Bernard G. Harvey, and Stanley G. Thompson (team leader)team leader Stanley G. Thompson in early 1955…"
"The number of atoms that would be produced would be approximately equal to the number of atoms of target material times its cross section times the ion beam intensity times the time of bombardment related to the half-life of the product when bombarding for a time of the order of its half-life." Too many times; reword to "The number of atoms that would be produced would be approximately equal to the product of the number of atoms of target material, the target's cross section, the ion beam intensity, and the time of bombardment; this last factor was related to the half-life of the product when bombarding for a time on the order of its half-life."
"…to obtain the needed intensity of 1014 alpha particles per second:; Seaborg applied for the necessary funds." Again, semicolon and not colon.
"The foil could be removed periodically and a new foil could be installed.replaced." Also merge with previous sentence with "and".
"The solution drops were collected on platinum disks. and dried under heat lamps." No middle full stop.
"Additional analysis and further experimentation, showed the produced mendelevium isotope to have mass 256 and to decay by electron capture with a half-life of 1.5 h." No comma.
"The lanthanides and actinides, in the metallic state, can exist as either divalent (for example,such as europium and ytterbium) or trivalent (most other lanthanides) metals."
"…suggesting that mendelevium(III) could be easily oxidized to mendelevium(IV), 1967 experiments with the strong oxidizing agent sodium bismuthate waswere unable to oxidize mendelevium(III) to mendelevium(IV)."
"…although experimental verification of this electron configuration washad not yet been made as of 2006."
"The ionic radius of hexacoordinate Md3+hashad been preliminarily estimated in 1978 to be around 91.2 pm:; 1988 calculations based on the logarithmic trend between distribution coefficients and ionic radius… Md2+ should have an ionic radius of 115 pm and hydration enthalpy −1413 kJ·mol−1:; Md+ should have ionic radius 117 pm." Two colon errors here.
"Sixteen isotopes of mendelevium are known, with mass numbers from 245 to 260:; all are radioactive." Colon error.
Production and isolation
"The mendelevium atoms would beare then trapped in a gas atmosphere (frequently helium), which would enter the vacuum chamber inand a gas jet from a small opening in the reaction chamber, carryingcarries the mendelevium along."
"…the mendelevium atoms can be transported over tens of metres to be chemically analyzed and have their quantity determined."
"Using the gas-jet method often renders the first two steps usually unnecessary."
"Another possible way to separate the trivalent actinides can be achieved byis via solvent extraction chromatography using bis-(2-ethylhexyl) phosphoric acid (abbreviated as HDEHP) as the stationary organic phase and nitric acid as the mobile aqueous phase."
"The mendelevium separated by this method has the advantage to beof being free of organic complexing agent compared to the resin column." Also merge with next sentence using a semicolon. ParclyTaxel 01:24, 7 August 2014 (UTC)
