A few other images are of low quality but it might be hard to find versions of higher quality: Ba (oxidises too easily), Pm, Ra, Pa (radioactives). A few images are only available as fair-use: Po, Np, Cm. It may be possible to find a free alternative (although it would be quite difficult).

Here's a site with some nice images and refs for structural data: . You could maybe even just export one (I mean, I know one can technically, just a licensing question of using a free applet and fact-of-nature data all hosted on a non-free website as the generator).

Images composed of simple shapes, lines, and letters such as those below should be recreated using vector graphics as an SVG file. These have a number of advantages, such as making it easier for subsequent editors to edit them, enabling arbitrary scaling at high quality, and sharp high-resolution renderings for print versions.
Molecular graphics is the discipline and philosophy of studying molecules and their properties through graphical representation. [1] IUPAC limits the definition to representations on a "graphical display device". [2]
An example of a full wallpaper name in Hermann-Mauguin style (also called IUCr notation) is p31m, with four letters or digits; more usual is a shortened name like cmm or pg. For wallpaper groups the full notation begins with either p or c, for a primitive cell or a face-centred cell; these are explained below.

It is free and open-source software, released under a GNU Lesser General Public License (LGPL). It is written in Java and so can run on the operating systems Windows , macOS , Linux , and Unix . There is a standalone application (editor), and two varieties of applet (editor and viewer) that can be integrated into web pages .
