The element photographs on the periodic table cards come from Wikimedia. All but one are public domain or carry a free licence, and each is credited to the person who took it. The exception is radon, marked non-free below: no free photograph of it glowing exists, so that thumbnail is used here under a claim of fair use for study, and its source page is linked. The drawings, the diagrams and everything else on this site are the site's own.
