This color periodic table with electron configurations contains each element’s atomic number, element symbol, name, and atomic mass in addition to electron configurations.
The full-sized image is 1920×1080 in size to make a nice wallpaper for widescreen devices. A PDF of this table can be used to print off a copy. Be sure to use ‘fit to page’ and ‘landscape’ for your print options and the results will be both readable and useful.
If you don’t have a color printer, the grayscale of this image is distinct enough to notice the differences between the element groups. There is also a black and white version of this table without element groups available.
If you would like a wallpaper where the background is not so bright, there is a version with a black background.
