Element with the longest half life
WebThe half-life of a radioactive element is the time it takes before half of the atoms in a sample of the element have decayed. If you know how many atoms you have in a sample, and you measure how many of them decay per second, it is easy to figure out how long you would have to wait before half of all the atoms have decayed.
