If you google for "siderophile tungsten" you get a lot of results. Also, my "Encyclopedia of the Solar System, Second Edition" by McFadden et al. 2006. I think it should be moved or, at least, explained why it's not siderophile. Does it have to do with pressure (siderophile in a planet core, not in the lab)?-- Zimriel ( talk) 20:32, 14 August 2008 (UTC)

While a bit of googling revealed that the provided explanations for the terms "lithophile", "siderophile" etc. ("Lithophile means 'silicate loving'.") are widespread, they seem pretty questionable to me from an etymological point of view. (for instance, I'm fairly positive "lithophile" should be literally translated as "rock loving") In that context, using a term like "means", implying a literal translation, is rather misleading. If that explanation is indeed frequently provided by scientific literature, I think it would be better to point it out as a commonly held misconception or handwave explanation. Anybody who can claim particular expertise in the field willing to look into it?

I don't have a source handy, but I am almost certain that, contrary to the claim that none of nitrogen's oxides are stable with respect to nitrogen and oxygen, aqueous nitrate is in fact the thermodynamically preferred state given redox conditions at the earth's surface, and only through biological processes ( denitrification and photosynthesis) are the elemental gases maintained in the atmosphere.

The last paragraph of the Chalcophile elements section should be heavily revised or deleted: these elements DO NOT constitute the bulk of commercially important metals (just think Fe, Al and Cr for example) and even if they did the reason given regarding the energy intensive purification methods is a non sequitur.
From a historical perspective I would concede the point when it comes to Cu however where clearly the ease of purification with charcoal, along with the relative abundance and ease of identification of its green (and some blue) mineral sources led to its prominence in human cultural evolution i.e. the bronze age — Preceding unsigned comment added by 110.33.214.194 ( talk) 16:25, 10 January 2012 (UTC)
Base on http://en.wikipedia.org/wiki/Abundances_of_the_elements_(data_page) :
- Ra, Ac and Pa are all more abundant than Rn and Po. However this article list these 3 as "very rare" and Po, Rn not. Why?
- Base on http://en.wikipedia.org/wiki/Astatine At has only ~28 g on Earth => much less than Ac, Pa, Ra, still included
- For Tc, Pm, Fr, Np, Pu: Francium 20 - 30 g, Promethium at least ~572 g (Occurence section). Tc, Pu, Np not yet found number.

The list on page 659 of Goldschmidt (1937) has five categories: siderophile, chalcophile, lithophile, atmophile, and biophile. This entry ignores biophile. In doing so, it follows the practice of most geochemists, but if this is an article about Goldschmidt's classification, the article should be complete. 198.137.20.82 ( talk) 13:17, 27 March 2015 (UTC)
This page has very long text lines that can't be wrapped to a shorter more readable width because of the large, very wide table. Isn't there a way the table could be made much smaller, with an option to pop it up full sized? The table is very nice with useful info, but it shouldn't dominate the page the way it does now. - Dough34 ( talk) 16:53, 15 May 2016 (UTC)
The table's color coding denotes silver and germanium as chalcophiles but silver and germanium appear in the section on siderophiles as well as in the section on chalcophiles—if not wrong at least confusing for readers without explanation.
The article's definition of siderophile:
The article goes on to list iron as a siderophile. It seems silly (and perhaps even wrong) to effectively state that iron can dissolve in itself. 71.219.211.90 ( talk) —Preceding undated comment added 13:06, 22 June 2017 (UTC)
