I needed the Periodic Table in vector format, so I decided to just draw one myself. If anyone else needs it as well, here is the Periodic Table of the Elements in Adobe Illustrator format.
My source for the data was from the International Union of Pure and Applied Chemistry (IUPAC), 2007 (http://old.iupac.org/reports/periodic_table/).
If you want to change the font, color, or size of all element properties at once, I have tagged each object type with its own Attribute Note (element_name, atomic_number, element_symbol, atomic_mass, box). For information on how to select objects with the same attribute note, please see my previous post on that topic: How to select the same sub-objects in multiple copies of a group in Adobe Illustrator
