Tube of uranium ore. This ore is from an old "ATOMIC ENERGY" chemistry set sold by Chemcraft in the 1950's. Radioactivity was popular back then. I got the chemistry set on eBay after consulting this trusty reference book about radioactive collectables. According to its table of going rate...
ELEMENT 90 of the Periodic Table, thorium, ordinarily appears as the first element of the actinide series, appended below cerium at the bottom of Table 1. This construction gives the impression that thorium is the second member of a series starting with actinium in the scandium group, just as...
