IDEA: When a radioactive isotope decays, it creates a decay product. By comparing the number of parent and daughter atoms in a sample, we can estimate the amount of time since the sample was created.

WebRADIOACTIVE DECAY The atomic structure for certain isotopes of elements is unstable. Radioactivity is the natural and spontaneous process by which the unstable atoms of an isotope of an element transform or decay to a different state, and emit or radiate excess energy in the form of particles or waves called radiation. WebSequential two-photon ionization is a process that is experimentally accessible due to the use of new free-electron laser sources for excitation.
