タイムライン

00:00:00 - 00:05:00
This video discusses radioactivity and radioactive isotopes, explaining the concept of radioactive series, which consists of various radioactive nuclides that decay into stable nuclides. There are four natural radioactive series: thorium, neptunium, uranium, and actinium. Each series has a specific starting point and ends with a stable nuclide, classified by mass numbers in patterns of 4n, 4n+1, 4n+2, and 4n+3. The half-lives and stable end products of these isotopes are outlined.
