WebJul 30, 2024 · This is a list or table of elements that are radioactive. Keep in mind, all elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. A good example of this is tritium, a radioactive isotope of hydrogen naturally present at extremely low levels. gitpython checkout tagWebAstatine is a dangerously radioactive element. Uses There are currently no uses for astatine outside of research. The half-life of the most stable isotope is only 8 hours, and only tiny amounts have ever been produced. A mass spectrometer has been used to confirm that astatine behaves chemically like other halogens, particularly iodine. gitpython checkout existing branchWebFluorine is the most electronegative element in the periodic table. This makes it one of the most reactive elements as well. This is because it is such a small atom. Halogens tend to react by gaining an electron to form a negative ion. Any incoming electrons feel a strong attraction to fluorine’s nucleus because the fluorine atom is so small. gitpython clone branchWebState the element in Period 3 that has the highest first ionisation energy.
