For example, the most common isotope of chlorine is 35, which accounts for around 75% of the atoms in chlorine. However, the isotope 37 accounts for arround 25% of all chlorine atoms. Therefore, the average atomic mass of all chlorine isotopes is:
(75+35) + (25+37)
---------------------- = 35.5
100
However, there is no isotope of chlorine with 35.5 nucleons, so the RAM of Chlorine is 35.
(75+35) + (25+37)
---------------------- = 35.5
100
However, there is no isotope of chlorine with 35.5 nucleons, so the RAM of Chlorine is 35.
