WebAstatine is the rarest naturally occurring element, and has no stable isotopes: the longest-lived has a half-life of just 8.1 hours. So no one has ever obtained enough of it to be visible to the naked eye. If that ever happens, new first-principles calculations published in Physical Review Letters predict that it will be a metallic solid. WebAnswer (1 of 2): Bulk statine has been predicted to have the electronic band structure of a true metal unlike boron, silicon, germanium, and tellurium which are semiconductors, and unlike arsenic and antimony which each have the electronic band structure of a semimetal and are each capable of for...
