WebHalf-Life of an Element. PRE-LAB DISCUSSION: Half-life. is the time required for half of the atoms of a radioactive isotope to undergo decay. Some isotopes are very stable, undergo decay very slowly, and have extremely long half-lives. Uranium-238 has a half-life of 4.46 . billion. years! Other isotopes are extremely unstable, and have short ... WebWe measure the decay constant, which can be done in a lab fairly easily. This is the constant we would normally use in computations, not the half-life. However, the half-life can be calculated from the decay constant as follows: half-life = ln (2) / (decay constant). To measure the decay constant, we take a sample of known mass and measure the ...
