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.
For example Clâ35 has an atomic mass of 35 u (17 protons and 18 neutrons), while Clâ37 has an atomic mass of 37 u (17 protons and 20 neutrons). In nature the different isotopes occur in different percentages. For example Clâ35 might make up 75% of all chlorine atoms on Earth, and Clâ37 makes up the remaining 25%.
