{"id":14,"count":8,"description":"The actinide series, or actinoid series, includes the 15 metallic chemical elements with atomic numbers 89 to 103. The name \"actinide\" derives from the first element in the sequence, which is called actinium. The actinides are all unstable, meaning they decay and release radiation.\r\n\r\nThe longer-lived actinides have half-lives measured in millennia or even millions of years. Uranium is the most familiar actinide because it is the heaviest naturally-occurring element and is used in nuclear reactors and weapons.\r\n\r\nThe other actinides are less well known but are important in various industrial and scientific applications.\r\n
