Most Radioactive Elements
The most stable naturally occurring element is Polonium. It is one of the most radioactive elements and has no stable isotopes. It is so radioactive that it causes gas particles around itself to excite and glow and so it appears to glow blue.
Radioactive Elements in Periodic Table
Radioactive Elements are the elements that emit radioactive waves like alpha waves, beta waves, and gamma waves. The Process is called Radioactivity. They are found throughout the Earth’s crust and have important applications in various fields, including medicines, energy production, etc. The radioactive elements are unstable because of the presence of excess nuclear charge inside their atomic nucleus. These atomic nuclei undergo radioactive decay to form stable nuclei. The elements that undergo radioactive decay are called radioactive elements.
