Including atomic numbers in this table would make it more useful.

[edit] Last natural element discovered?

This article says Francium was the "last naturally occurring element discovered" (1939), then says Astatine was discovered in 1940. But the article on Astatine says it is naturally occurring (in the second sentence). Could this apparent contradiction be fixed please? McKay 01:12, 17 October 2006 (UTC)

[edit] Beryllium

I don't know much about the history of the discoveries of elements, so I don't know why berylium is listed twice: 1798 and 1828. Just thought I'd point that out to anyone who is interested in the subject and would like to research it. --DangApricot 03:38, 18 October 2006 (UTC)

[edit] Ununoctium

Ununoctium appears to have been discovered twice. There should be only one instance of discovery on the chart, right? - Unsigned

[edit] Oxygen

Should it perhaps be noted that Scheele discovered oxygen a few years earlier than Priestly, but did not publish the discovery until 1777? On the page Carl Wilhelm Scheele it is also stated that he "also discovered other chemical elements such as barium (1774), chlorine (1774), manganese (1774), molybdenum (1778), and tungsten (1781)". This is in disagreement with what is said in these tables. Myself, I am not familiar enough with the history to be of much help, but it seems to me both pages cannot be right...

That should be clarified, yes. —Nightstallion (?) 02:54, 5 November 2006 (UTC)

Gold is missing from the list of elements known in antiquity.
