How many electrons are in astatine
WebThe ions have a stable arrangement of electrons, with a complete outer shell. ... Astatine is below iodine in group 7. Use the information to predict the reaction of astatine with hydrogen. Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of 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 radioactivity.
