So, here is a second revision of the Mendeleev's table-wallpaper.
Changed: some mistakes in electronic structures and readability of
them. Metal/Non-metal sign on a right place now. A bit too busy to
change them all so I am posting with in my favourite blue colour and
in three popular sizes: 1680x1050, 1920x1080 and 1440x900.
Thank you all for your letters and special thanks to Dominic( daj198 ) for his corrections.
From now on(31.01.2012) all these wallpapers with PROPER SIZES I placed here: periodictablewallpaper.com/
