All elements contain protons and neutrons , located in the atomic nucleus , and electrons that orbit around the nucleus Figure 5a. Th and U also give rise to radioactive series -- different series from that of U, containing different isotopes and ending in different isotopes of lead. As time goes on, atoms of Rb87 decay to Sr, resulting in a change in the Rb From Wikipedia, the free encyclopedia. This is the foundation of the periodic table of the elements, a basic part of chemistry that has stood without challenge for a hundred and fifty years. Which brings us to the third method of radiometric dating.
