The half-life: the length of time taken for half of the atoms in the sample to decay constant for a particular event ie elementshave known half-lives half-lives vary between different radioactive elements from seconds to billions of years a sample of isotope's activity can be plotted against time on a graph to. Most of them are radionuclides, meaning they are unstable and undergo radioactive decay there are nearly 4000 known isotopes and 580 nuclear isomers.
