For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
Average atomic weight = 26.4 amu + 9.05 amu = 35.5 amu. Notice that the average is determined by the more abundant Chlorine-35. Because chlorine-35 is more common, the average is closer to 35 amu than 37 amu. Clearly no atoms of chlorine actually have a mass of 35.5 amu.The tabulated value in the periodic table is a statistical creation and matches no real chlorine atoms at all.ecause chlorine-35 is more common, the average is closer to 35 amu than 37 amu. Clearly no atoms of chlorine actually have a mass of 35.5 amu. The tabulated value in the periodic table is a statistical creation and matches no real chlorine atoms at all.
