  1. One of the few elements that readily bonds with gold. Exposure to it can cause "tellurium breath," a garlic-like odor that persists for weeks.
  2. Often confused with graphite (plumbago) in antiquity, its name comes from the Greek word for "lead," though it contains none.
  3. Its symbol comes from the Latin stibium, but its name likely derives from Greek words meaning "a metal not found alone." Ancient Egyptians used its sulfide as eyeliner.
  4. Long mistaken for tin or lead, this post-transition metal is more diamagnetic than any other metal and has a half-life longer than the estimated age of the universe.
  5. The final member of the Lanthanide series, it was the subject of a naming dispute between French, German, and American scientists in 1907.
  6. This is the most reactive of the rare-earth metals; it’s the reason your banknotes glow under UV light to prevent counterfeiting.
  7. The densest naturally occurring element. It smells faintly of chlorine due to the formation of its highly toxic tetroxide.
  8. Known as the "poisoner's poison" because it is colorless, odorless, and tasteless. Its name comes from the Greek thallos, meaning a green shoot or twig.
  9. Its name literally translates from Greek as "hard to get at," fitting for a Lanthanide discovered via fractional distillation of holmium oxide.
  10. Part of a "twin" pair with Praseodymium; when combined with iron and boron, it creates the strongest permanent magnets commercially available.
  11. Named after the moon, this element's conductivity increases with light intensity, making it vital for early photoelectric cells.
  12. Predicted by Mendeleev as "eka-aluminum," it has the widest liquid range of any metal and will melt if held in a warm hand.
  13. Named after the mythological founder of Thebes, this element is often found in "Yellow" pigments but is notorious for causing "Itai-itai" disease.
Down
  1. Named after the Latin name for Copenhagen, it was the first element discovered using X-ray spectroscopy rather than chemical means.
  2. The "Tiger of Chemistry." It is the most electronegative element and was so dangerous to isolate that it killed or blinded several 19th-century "Fluorine Martyrs."
  3. Named after a Greek mythological figure punished with eternal thirst, fitting for a metal that is completely "impervious" to immersion in acid.
  4. Named for the brilliant indigo line in its spectrum, this soft metal "screams" (a high-pitched tin-cry) when bent.
  5. The most corrosion-resistant material known, its name comes from the Greek goddess of the rainbow due to the striking colors of its salts.
  6. Named after an asteroid (which was named after a Greek goddess), this metal can absorb up to 900 times its own volume in hydrogen gas.
  7. The last naturally occurring stable element to be discovered (1925), it has the third-highest melting point behind carbon and tungsten.
