## Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Tantalum. Additional text was taken directly from USGS Tantalum Statistics and Information, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (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.

## Capacitance

In case anyone wonders about my "capacitance" edit: it is not correct to say that tantalum has a higher capacitance than other substances (as the pre-edit version did). Capacitance is a property of an electronic component, not of a material; it would be like saying that titanium has a higher velocity than iron. (Sure, if you build a high-performance jet out of it, but...) I substituted what I think the author of that sentence probably meant, which is that tantalum's main electronic application is in capacitors with high capacitance.129.97.79.144 21:11, 2 Jun 2005 (UTC)

Absolutely makes sense even without an explanation. Femto 17:48, 3 Jun 2005 (UTC)

## Abundance/rarity

Hello, The introduction to the article says "Tantalum is a rare metal, comprising just ${\displaystyle 8*10^{-9}}$% of the universe, making it fifteen times less abundant in the universe than gold (which makes up ${\displaystyle 6*10^{-8}}$%)". However, ${\displaystyle 8*10^{-9}*15=12*10^{-8}}$, not ${\displaystyle 6*10^{-8}}$. It wasn't clear whether the abundance of tantalum, abundance of gold, or the "fifteen times less abundant" was incorrect. Can someone verify and edit this? — Preceding unsigned comment added by TheWurstPuns (talkcontribs) 14:29, 10 April 2015 (UTC)
