Solution The rate of radioactive decay is expressed by the relationship: k = 0.693/t 1/2 where k is the rate and t 1/2 is the half-life. Plugging in the half-life given in the problem:
WebApr 17, 2016 · The half-life is the amount of time for the material to decay enough to lose 1/2 of its radioactive nuclei. The multiplier is 1/2. We will raise that by the number of years … 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.

WebTo begin, we’ll count the number of half-lives that have passed. This can be obtained by doing the following: Half-life (t½) = 2.4 mins Time (t) = 7.2 mins Number of half-lives Number of half-lives n = t t 1 / 2 n = 7.2/2.4 = 3 Thus, three half-lives have passed. Finally, we will calculate the remaining amount.
