To Merge Or Not To Merge (Neutrium And Polyneutron)
edit- The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.
Opposer: I do not think that these two articles shall be merged into one. I think it will be easier to keep track if the articles are seperate.
The discussion above is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.
Adding The Infobox To The Neutronium (Neutrium) Page
editAnonymous: The Infobox on the right of this page should be added to the Neutronium (Neutrium) page, for it is often described as an element in many contexts.
