The number of elements has been changed from 92 to 94, can someone explain? I thought Uranium (92) was the last naturally occuring element. Where did the other 2 come from? -- Tango 16:54, 24 Apr 2004 (UTC)

Neptunium and Plutonium were found to occur in trace amounts due to Uranium decomposition.

Fair enough. That should probably be mentioned in the article, as 92 is more commonly known, AFAIK. -- Tango 11:48, 25 Apr 2004 (UTC)

[edit] Clarification

"Atoms ... have diameters of about 10-8."

10-8 (the "-8" is an exponent, of course) what? Centimeters?
