WebThis time interval may be thought of as the sum of the lifetimes of all the individual unstable nuclei in a sample, divided by the total number of unstable nuclei present. Generally, mean life or average life is designated as τ. So, τ = (Life of 1st Atom + life of 2nd Atom + … + life of N0th atom) / N0. Mathematically, it can be shown that ... WebJan 27, 2024 · Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope. By measuring the ratio of the amount of the original radioactive element to the daughter isotope ...
