DescriptionPeriodic Table Radioactivity.svg	English: Periodic table with elements colored according to the half-life of their most stable isotope. Elements which contain at least one stable isotope. Radioactive elements: the most stable isotope is very long-lived, with half-life of over four million years. Radioactive elements: the most stable isotope has half-life between 800 and 34.000 years. Radioactive elements: the most stable isotope has half-life between one day and 103 years. Highly radioactive elements: the most stable isotope has half-life between several minutes and one day. Extremely radioactive elements: the most stable isotope has half-life less than several minutes. Very little is known about these elements due to their extreme instability and radioactivity.
