Half life radioactive isotopes worksheet
WebFeb 20, 2024 · The answer can be found by examining Figure 31.5. 1, which shows how the number of radioactive nuclei in a sample decreases with time. The time in which half of the original number of nuclei decay is defined as the half-life t 1 / 2. Half of the remaining nuclei decay in the next half-life. Further, half of that amount decays in the following ... Webhalf-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half. The …
