Hi all, I have a small question. I have checked it: http://neon.chem.ox.ac.uk/vrchemistry/LiveChem/transitionmetals_content.html [Broken] and I am very confusing. There is some kationts of metal and these are liquid ! For example mangan kationt : Mn+7 is red liquid. Is it possible ? PS:I am sorry for my englisch, its not good !
