Astatine Cube Element Sample Historical Artifacts The display incorporates aspects ofAstatine's atomic number is 85 and its symbol is At. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of the astatine's isotopes are short lived; the most stable is astatine 210, with a half life of 8. 1 hours. A sample of the pure element has never been assembled, because any macroscopic specimen would be immediately vaporized by the heat of its own radioactivity.
