The atomic number corresponds to the number of protons in an atom.Atomic mass is a combination of the number of protons and neutrons in the nucleus.If this assumption is not true, then the method will give incorrect dates. If the production rate of C in a specimen difficult or impossible to accurately determine. Willard Libby, the founder of the carbon-14 dating method, assumed this ratio to be constant.

An “isotope” is any of several different forms of an element, each having different numbers of neutrons.The variation is certainly partially the result of a change in the cosmic ray production rate of radiocarbon.The cosmic-ray flux, and hence the production rate of C-14, is a function not only of the solar activity but also of the magnetic dipole moment of the Earth.4Though complex, this history of the earth’s magnetic field agrees with Barnes’ basic hypothesis, that the field has always freely decayed....The illustration below shows the three isotopes of carbon.

Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.

Assumptions in the scientific community are extremely important.
