I just finished writing an article for answers.com about trends in the periodic table, a topic I'm obviously comfortable with (and many of the readers of this blog are as well). To be honest I checked the trends with wikipedia and other sources many, many times - worried that somehow I had forgotten them.

It was a chance to rethink about the periodic table, though, which was fun. Mendeleev's work is pretty impressive. Being able to predict new elements the way he did was amazing (and will most likely be the subject of a future article).

So tell me, readers, What do you think is most impressive about the periodic table? What is outdated or needs changed? Do you prefer any of the "alternate" forms of the periodic table?
