Characteristics of the Carbon Isotopes

The isotopes of an element have the same atomic number Z, i.e., the same number of protons and electrons and the same electron configuration. 

However they have a different number of neutrons, and therefore a different mass number the mass number (or atomic weight) is the sum of the protons and neutrons, represented by the symbol A . 

The element carbon has seven isotopes, which are listed in Table 2.6. The most common isotope by fcir is which has six neutrons. The others

Investigations carried out with the aim of establishing characteristics of the carbon isotope composition of the carbonate cement have shown that the Triassic reservoirs overlying the Lower Paleozoic silty-sandy complex (Cambrian-Ordovician) exhibit the following features ...
