UCLA Periodic Table (Proposed)

Eric Scerri writes:

During an office hour here at UCLA with a couple of students – Annelise Gazale & Chidinma Onyeonwu – we came up with a 'new periodic table'.

The basis of it is related to a point you frequently make against the Left Step formulation, namely that it messes up trends in atomic radius etc.

So how about this: Traditionally on the right side of the table elements become less reactive as we move down, but on the right side of the table elements become more reactive as we move down. Consequently, the noble gases are anomalous in the way they usually sit since they become more reactive as we move down the table.

Ergo: Move the noble gases to the left edge of the table. (Yes, this has been done before of course but not for this reason.)

Thanks to Eric Scerri for the tip! See the website EricScerri.com and Eric's Twitter Feed.
