Yeah so neodymium is one my favourite f elements to work with. When you use it in compounds and you dissolve it, often you get colourful blue solutions from it. Sometimes they are green as well, but often I have found that if concentration of the solution makes a really big difference to the colour of these solutions so you may have a compound whic...
