TWG

The article refers to the "TWG". This needs an explanation. --Slashme (talk) 07:30, 5 February 2008 (UTC)

Oxidation state 7?

The further text gives support for state V. I think oxidation state shouldn't be confused with group number ... L8R. Said: Rursus ☻ 06:56, 25 May 2008 (UTC)

Oxidation state was 7; the sårce speax ab8t BhO₃Cl, not BhOCl₃. I fixed the formula error accordingly. Said: Rursus ☻ 11:15, 25 May 2008 (UTC)

On ²⁷⁴Bh's half-life

Isotope ²⁷⁴Bh was recently added to this article with a half-life of 1.3 min. However, the source given for it only seems to refer to a "lifetime" of 1.3 min for the single nucleus of this isotope that was produced. This would translate to an expected half-life substantially lower (1.3 min*ln(2)≈1 min) (with large error bars, of course), not making it the longest-lived isotope. So I think this should be corrected. --Roentgenium111 (talk) 17:40, 5 April 2011 (UTC)

Why is it "*ln2"? If you think you are right, then feel free to go ahead and change it. I am not aware of the conversion details from one event to a population average, so I trust your judgement on this one. Nergaal (talk) 02:22, 13 April 2011 (UTC)

ln2 is a conversion factor between the half-life (1/2 intensity decay) and lifetime (1/e intensity decay). I am going though articles which used that reference and correcting the values. Materialscientist (talk) 05:11, 13 April 2011 (UTC)

Thanks for pointing that out. I never noticed the subtle difference until now, but you are right. Nergaal (talk) 16:50, 14 April 2011 (UTC)

half-life not long enough for chemical and some physical properties to make sense

I've deleted the following entries from the elementbox. Not only could I not find evidence for them in the cited sources, but it seems dubious that something with a half-life of 22 seconds could form crystals, molecules, etc, enough to measure these.

appearance : unknown, probably silvery
white or metallic gray

phase : presumably a solid

crystalstruct : hexagonic

oxistates : 7, 6, 5, 4, 3, 2, 1, −1, −2, −3

Don't know if it is necessary to issue a (partial) correction after so many years, but forming compounds and crystals is possible in a lot less than 22 seconds. It is fine to list things like that if we have sources, and we don't just blindly follow periodic trends (which can be affected by things like relativistic effects).
