Data 2003

This article is part of Wikipedia:Wikiproject Isotopes. Please keep style and phrasings consistent across the set of pages. For later reference and improved reliability, data from all considered multiple sources is collected here. References are denoted by these letters:

A 729, pp. 3-128 (2003). — Where this source indicates a speculative value, the # mark is also applied to values with weak assignment arguments from other sources, if grouped together. An asterisk after the A means that a comment of some importance may be available in the original.

Ok, both Xenon and Caesium say that they are second in the number of isotopes. Caesium says it's second to Xenon, Xenon is second to tin.

One says "isotopes" the other stable isotopes. So this is not absolutely contraditory, but perhaps some phrasing might be in order to clear this up?
