Strictly it is the half life of a particular isotope of the element.
The half life of a radioactive isotope is the time taken for the number of radioactive atoms in the sample to decay to one half.
Half lives vary hugely, from times like 10-21 seconds, to the very long, approaching the age of our solar system at 4.5x1012 years.
