[edit] Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Rhenium. Additional text was taken directly from USGS Rhenium Statistics and Information, from the Elements database 20001107 (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

I think data of rhenium in english and in spanish don´t mach (see melting heat in both pages)

I'm concerned regarding two conflicting pieced of information. 1) The page states Rhenium is not naturally found on Earth, 2) followed by a statement regarding it's 'most natural state'.
How can it have a most common state, when it is NOT naturally found on Earth? Ferbutt (talk) 21:34, 27 May 2008 (UTC)ferbutt
- It doesn't say it's not found on Earth. It says "Rhenium is not found free in nature". The key word is free. That means that it is found only as part of a compound. The same is true for most elements, including sodium and chlorine, for example. --Itub (talk) 12:07, 30 May 2008 (UTC)
[edit] occurance
"Rhenium (Latin Rhenus meaning "Rhine") was the last naturally occurring element to be discovered."
Even if it is in only small quantities, samples from technetium have been extracted from pitchblende from Belgian Congo. The discovery of technetium was confirmed in 1937.
It says that rhenium was the last naturally occuring element to be discovered -- and then later that it was the next-to-last naturally occuring element to be discovered. Which is true? (I am leaning towards next-to-last; I believe francium was the last element to be discovered in nature). Bbi5291 00:49, 26 August 2007 (UTC)
I changed it to "next to last", so it is consistent within the article. Francium was discovered later, and the article about francium claims that it was the last naturally ocurring element to be discovered. The difference seems to stem from "naturally" meaning "can be found in nature" vs. "naturally" as in "has a stable isotope". Francium has no stable isotope and all its isotopes are rather short lived with the most stable having a half life of 21.8 minutes (information from the article about francium). 149.156.124.12 11:17, 15 November 2007 (UTC)
