Many of the elements on the periodic table have ‘isotopes’ that have the same chemical properties with different mass numbers. The different ratios of these isotopes can be measured in many of the chemical components that make up gases, oils, contaminants, and water. Often, the isotope ratios...

Isotopes: atoms of the same element with the same #p but different #n (and thus different atomic mass) are called isotopes. Since isotopes have different masses, the average atomic mass of all isotopes of the element is listed on the periodic table, henc
The interpretation of the curious mass of chlorine awaited the discovery of the neutron by James Chadwick in 1932. Although all chlorine atoms have 17 protons, different isotopes of the element have different numbers of neutrons. In Table 1, the mass numbers of the chlorine isotopes are denoted...
