While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and radioactivity.An atom that has different number of neutrons but the same number of protons.Relatively chemically inert with a hardness of 8.5.This can be further calculated for a series of half-lives as shown in the table.The table does not show more than 10 half-lives because after about 10 half-lives, the amount of remaining parent is so small it becomes too difficult to accurately measure via chemical analysis.
