I am certainly no expert but I have seen references to +2 and even + 3 under some circumstances. Sorry I cant offer a solid cite.

A metal of higher valance can replace a metal of lower valance in the enzyme complex, preventing the enzyme from functioning normally. Silver, with a valance of plus 2, can replace many metals with a lower, or equal valance that exhibit weaker atomic bonding properties." That is not correct. Silver has only one valence, which is +1. Hopefully that is the only significant error in the article. Kevin Nolan [email protected] <mailto:[email protected]>
