The addition of four new elements added to the periodic table in 2016 was only the beginning. Now chemists and physicists are starting the hard work of determining the physicochemical properties of these short-lived and incredibly rare species. And that often involves atom-at-a-time chemistry.
Glenn Seaborg was born too late to have spawned Cal’s spirit cry. It’s coincidence, surely, that his name is an anagram for “Go Bears!” And, although he was definitely a Bears fan and was Chancellor when Cal last made it to the Rose Bowl in 1959, he was never in Oski’s league as a campus celebrity. While others led rallies, he had to settle for spearheading decades of trailblazing nuclear science, endowing UC Berkeley with bragging rights to the discovery of a record 16 new elements. Now, though, the 1951 Nobelist is making a bid to play in the social media space.
The story of the fifteenth element began in Hamburg, in 1669. The unsuccessful glassblower and alchemist Hennig Brandt was trying to find the philosopher’s stone, a mythical substance that could turn base metals into gold. Instead, he distilled something new. It was foamy and, depending on the preparation, yellow or black. He called it “cold fire,” because it glowed in the dark. Interested parties took a look; some felt that they were in the presence of a miracle. “If anyone had rubbed himself all over with it,” one observer noted, “his whole figure would have shone, as once did that of Moses when he came down from Mt. Sinai.”
