Article changed over to new Wikipedia:WikiProject Elements format by mav 09:06, 2 Mar 2004 (UTC). Elementbox converted 11:54, 17 July 2005 by Femto (previous revision was that of 07:47, 14 July 2005).
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Einsteinium. Additional text was taken directly from the Elements database 20001107 (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table were obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but were reformatted and converted into SI units.
Why is it claimed to be both the seventh trans-uranic element and the seventh actinoid ? That doesn't look right. It looks like it should be the eleventh actinoid.Eregli bob (talk) 04:47, 15 February 2009 (UTC)
Considering that Einsteinium and Fermium were both created in the explosion of a thermonuclear bomb, and that supernovae are far more powerful than any bomb that has ever been created, wouldn't it make sense that these elements may exist in trace amounts in supernova remnants? --Ferocious Flying Ferrets 19:45, 9 April 2010 (UTC)
Isotopes produced in thermonuclear explosions
Es-254 (& Fm-254) are not produced in thermonuclear explosions since the beta decay chain ends at Cf-254, which does not undergo beta decay (it decays by spontaneous fission or, rarely, by alpha decay). (Similarly, Fm-253 is not produced either since Es-253 never decays by beta decay.) 126.96.36.199 (talk) 06:42, 30 January 2011 (UTC)
- The article does not say it is produced, upon a brief look. Materialscientist (talk) 11:11, 30 January 2011 (UTC)
In the History section it states, "Some 238U atoms, however, could absorb another amount of neutrons, most likely 16 or 17, resulting in the 254Es and 255Es isotopes, respectively." (The following sentence says, "...also resulted in the 253Fm...".) 188.8.131.52 (talk) 02:56, 31 January 2011 (UTC)

This is my first review...I have no idea of what to expect. But still, you can leave comments and I will address them. Check out my peer review as well. Good luck, editors. FREYWA 02:24, 4 April 2011 (UTC)
Ready to review.
- Is it reasonably well written?
- Is it factually accurate and verifiable?
- Is it broad in its coverage?
- Is it neutral?
- Fair representation without bias:
- The 4th criterion is equivalent to not looking like anything. And this article does.
- Fair representation without bias:
- Is it stable?
- Does it contain images to illustrate the topic?
- Pass or Fail:
Specifically, for section 1A, in the section on organomettalic compounds it says, "So experiments, have been performed..." and the comma there is something I want you to fix. For section 3B the section on the synthesis in nuclear explosions is a wall and looks intimidating. FREYWA 08:09, 5 April 2011 (UTC)
Hold it - where is the a parameter for EsOCl (look at Chemical compounds → Halides → the last paragraph)? The prose is really good. Remove that "a = " and I will list einsteinium as a good article soon. I have to remove the a parameter myself. Then it will be a good article. FREYWA 08:13, 8 April 2011 (UTC)
Einsteinium was actually used for something! The Surveyor 5, 6, & 7 lunar landers carried an instrument that analyzed the chemical composition of the moon by measuring the energy of alpha particles from Cm-242 after they bounced off the lunar surface. Es-254 was "placed near the detectors as an energy marker" (Science vol. 158 p. 635). 184.108.40.206 (talk) 07:01, 7 April 2011 (UTC)
- OK, then cite it and include it! FREYWA 08:24, 8 April 2011 (UTC)

- I've added information about that name to the lead. Double sharp (talk) 12:43, 19 January 2012 (UTC)
- Removed. There is no evidence it is used, or was used more than a few times. The corresponding text in  is vague and is referenced by an unreliable source. If properly sourced, this might be considered for the "History" section, but not for the first line of the lead. Materialscientist (talk) 12:53, 19 January 2012 (UTC)
No Natural Isotopes?
This article states that no isotopes of Einsteinuim occur in nature. However, in the Isotopes section of Californium's infobox, it show 253Cf as occuring in trace amounts in nature, presumable due to random transmutation/multiple neutron capture. However, several sources confirm that this isotope beta minus decays ~99.69% of the time into 253Es. Wouldn't this count as naturally-occuring Einsteinium?
- I asked this already in WikiProject_Elements last year, but didn't get a definite answer, unfortunately... --Roentgenium111 (talk) 17:45, 24 August 2013 (UTC)
