If you had an ensemble of identical particles, the probability of finding a given one of them still as they were - with no decay - after some time is given by the mathematical expression This governs what is known as the "decay rate." The rate is unique to different particles and so to different atomic elements.

Decays are very random, but for different elements are observed to conform to statistically averaged different lifetimes.One example of this can be found in metamorphic rocks.This does not mean that all rock samples are unreliable, but it is possible to account for a process which throws off the data for metamorphic rocks.There is no reason to expect that the rate of decay of a radioactive material is largely constant, As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.The energy locked in the nucleus is enormous, but cannot be released easily.
