Radioactive decay is governed by the laws of chance. An atom decaying is a random, spontaneous process. The more atoms there are in a given sample, the more chance there is that one will decay. …

The decay of a radioactive element is a random process which is governed by the laws of chance. The rate of decay only depends on the number of undecayed atoms. This means that the more atoms of …
