Actinide?
What kinds of things contain the elements that are in the actinide series?
- The actinide series encompasses the chemical elements that lie between actinium and lawrencium on the periodic table with atomic numbers between 89 and 103 inclusive.
Exactly where the sequence of actinides begins and ends is actually open to debate. Various sources make different and often seemingly arbitrary choices. Thus I feel justified in changing this article for consistency with Wikipedia's own version of the periodic table.

"Between" implies exclusive. We should either say "between Radium and Rutherfordium" or "between Actinium and Lawrencium, inclusively." ---Ransom (--71.4.51.150 19:01, 25 January 2007 (UTC))
lanthanide and actinides
See the, modfifcation I have proposed in French (my English is not good enough for on line modifying): Lanthanides and Actinides are similar, only when they are at the same oxidation state. This make difference for Pa, U, Np, Pu and Am, which can be stable at +5 and/or +6 oxidation states, while Lanthanides cannot be oxidised that much.
Wikipedia's version of the periodic table has been changed to conform to IUPAC. Flying Jazz 02:00, 23 Jun 2005 (UTC)
- I changed the article (and lanthanide-article) to use IUPAC convention and to make it consistent with Wikipedia peridic table. --Levil 02:05, 23 August 2005 (UTC)
Lawrencium
It never seems to make sense to include Lawrencium in the series.
