Oct 11, 2019 · OK, let's talk about something with pretty much no practical relevance whatsoever: the element copernicium. That's #112, just below mercury in the periodic table, and its longest-lived isotope has a half-life of 29 seconds. Which is actually pretty impressive - that's one of the longest-lived elemen
