New Graphical Representation of the Periodic Table 140
KentuckyFC writes "The great power of Mendeleev's periodic table was that it allowed him to predict the properties of undiscovered elements. But can this arrangement be improved? Two new envisionings of the periodic table attempt to do just that. The first uses a new graphical representation that shows the relative sizes of atoms as well as their groups and periods. The other uses the same kind of group theoretical approach that particle physicists developed to classify particles by their symmetries (abstract). That helped particle physicists predict the existence of new particles, but may have limited utility for chemists who seem to have discovered (or predicted) all of the elements they need already."

Another periodic table, is not news.
Someone should have already linked one of the periodic table databases like:

Yeah, but remeber, it's from Microsoft Research. They're innovators, dammit!
Not only have the patented the round table, they've also patented the time machine they're going to use to back in time and sue Erdmann and Mendeleev.
And then King Arthur.

The major problem I see with it is they stitched the table ends together rather than really account for size. You have to know the previous one to make any sense of the new one.
Take the first inner ring: it LOOKS like it goes B - C - N - O - F - Ne - Li - Be... and that puts 10 right next to 3.
Makes sense if you KNOW to start counting at Lithium, but if you're just looking at the table, you will naturally start at Boron. More annoyingly is that puts a very unreactive element first. The great part about the old one is it went from very reactive, to minimally reactive, to very reactive (with a brief stop to inertsville). Again, you lose that having the top line bookended by Boron and Beryllium.

The really interesting table on that site is this one: ... Did Mohd rip off Wikipedia?
http://www.meta-synthesis.com/webbook/35_pt/pt_database.php?PT_id=35 [meta-synthesis.com]
Which is labeled "Wikipedia table" and dated 2006
Fortunately for him, wikipedia's history traces back to this revision [wikipedia.org] which was apparently made by Mohd Abubuakr himself, back in August 2006. He was in school at the time, at Jawaharlal Nehru Tech [linkedin.com]. According to his LinkedIn profile, he's not so much a green field researcher as he is a techie ... Performance and Security consulting. The article is a little misleading ... makes it sound like MS research has a skunk works in Hyderabad trying to invent a new periodic table.
His blog is cute too. A little emo, a little egotistical, but seems like a nice guy. I wonder what his /. handle is.

Just wow. I didn't see yet how they account for the overlap between d/p/s/f.
