Nuclear Half Life at Life

Nuclear Half Life. There is no way of forecasting when a single unstable nucleus will decay. The activity of radioactive material depends upon the amount of material present and decreases with time as the nuclei decay to another state.

This value does not depend on the moment chosen: It has been determined that the rate of radioactive decay is first order. The amount of time taken for the nuclei to halve will always be the same.

O how long ago the earth was created o how long you have been watching this video o how long it takes for an electron to become a proteon o how long it takes a nuclear process to ocur. Exponential decay can be expressed mathematically like this: From the above discussion it is found that the estimate of any radioactive element can be. The time taken by a substance to become half of its initial mass through radioactive decay is measured as the half life of that substance.
