An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element.The nuclei of most atom s contain neutrons as well as protons.2) To familiarize students with the concept of half-life in radioactive decay.3) To have students see that individual runs of statistical processes are less predictable than the average of many runs (or that runs with relatively small numbers involved are less dependable than runs with many numbers). Students not only want to know how old a fossil is, but they want to know how that age was determined.
These are the most common naturally occurring isotopes of oxygen and carbon, respectively. An atom of carbon-14 contains 6 protons and 8 neutrons and is denoted Certain isotopes of elements are unstable, giving off ionizing radiation, also known as radioactivity. Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.
