Interpretation: To determine experimental age of the
Concept introduction:
Isotopes:
These are the atoms of the similar element which contains the different number of neutrons and same number of protons.
For example:
Isotopes of atoms with unstable nuclei are called radioisotopes.
Radioactive decay: Unstable isotopes release particles and produce energy to become stable isotopes.
An element undergoes radioactive decay process it changes into a different isotope of the similar element or into an entirely different element after radioactive decay.
Half life:
The half lives of known radioactive isotopes vary from about
The longer the half life , the lower the decay constant.
