3. What is astatine  Astatine is a highly unstable radioactive element, the heaviest of halogen series.  It’s the longest lived isotope has a mass number of 210 and a half-life of 8.3 hours  Astatine is like uranium but less unstable.

4. How it was created  In 1940 Doctor Corson discovered Astatine in The University of California with his friends Emilio Serge and K.R. Mackenzie  They created the Astatine by creating small amounts of Bismuth-209 with accelerated alpha particles.

5. Where you can find it  Astatine is found in uranium and thorium materials but in extremely low concentrations.

6. Uses for Astatine  Astatine is use for nuclear medicine like Cancer treatment.  Also Astatine is used for targeted alpha particles radiotherapy.  Since Astatine is like Iodine, it is also a treatment is also is use for thyroid treatment.

7. Facts  Astatine is the 85 th element in the periodic table.  Astatine is in the Group 17 (VIIA).  Astatines symbol is AT.  Astatines atomic weight is 209.9871.  Astatine in Greek is “Astatos”.  The boiling point is 610 degrees Fahrenheit.
