During mean life of a radioactive element

WebHalf-Life is normally defined as the time needed by a radioactive substance (or one half the atoms) to disintegrate or transform into a different substance. The principle was first … WebThat means, the half-life of a radioactive element is inversely proportional to the radioactive constant or decay constant of that element. In order to disintegrate 1 g of uranium to 0.5 g of uranium, it will take 4500 million years. It will take another 4500 million years to disintegrate thus 0.5 g uranium to 0.25 g. So, the half-life of ...
