Wikipedia:Articles for deletion/Unsolved problems in chemistry
No opinion on deletion/inclusion, but this article as it stands has serious fundamental flaws from a Wikipedia article standpoint, namely what criteria is determining that a particular problem should be listed here and where are the |reliable sources |establishing that these are "persistent questions with deep implications"?  I've tagged the article and if it is indeed kept these problems need to be addressed
