- The Nuclear physicists have detected the radioactive disintegration of a rare iso tope of astatine for the first time.
- They have measured the proton emission and half-life of 188Astatine (188At).
- This shows that the heaviest element found in nature may be modified a lot, maybe even destroyed, in a way that scientists didn't predict.
- Astatine (At) is a radioactive, halogenous element with atomic number 85 and with 103 neutrons.
- It was belonging to the halogen family (Group 17) on the periodic table.
- It is a rarest natural element on the Earth, not naturally occurring in significant quantities due to its short half-life.
- This was the first recorded instance of proton emission from astatine, a rare and heavy element.
