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.
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.
Where you can find it Astatine is found in uranium and thorium materials but in extremely low concentrations.
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.
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.
Glossary Bismuth- a chemical element Alpha Particles- when 2 protons and neutrons are bonded together into a particle. Radiotherapy- commonly applied to the cancerous tumor because of its ability to control cell growth Greek-A language used in Greece.
Glossary part 2 Atomic weight-the weight of atoms in a element. Isotope-One of two or more atoms having the same atomic number but different mass numbers. Lodine-A trademark used for the drug etodolac. Group 17-The halogens or halogen elements
Glossary part 3 Halogen-A chemical element that makes light bulbs.
