The penultimate elements infographic focuses on the Actinides. Many of these elements don’t occur naturally, and are produced synthetically, with some of them existing only for a fraction of a second before they decay back into lighter elements.
With this in mind, it’s been becoming harder to find a range of uses or interesting facts for every one of these elements, so here I’ve started looking more at dates of discovery and the scientists that some of the elements inherit their names from. Elements like Einsteinium are, of course, relatively obvious, but the name of Ernest Lawrence might have a few non-scientists scratching their heads.
