Could a superheavy element be a lead alternative?
A few sentences later:
the best-suited isotope exists for only about 20 hundredths of a second
And that's the problem with every superheavy element so far synthesized. Half life measured in milliseconds, and even enormous expensive equipment produces only a handful of atoms. Interesting stuff, but industrial application will be elusive at least until the "island of stability" is reached.
the “island of stability” is made of Unobtanium.................
