Chlorine consists of two major isotopes, one with 18 neutrons (75.77 percent of natural chlorine atoms) and one with 20 neutrons (24.23 percent of natural chlorine atoms). The atomic number of chlorine is 17 (it has 17 protons in its nucleus).

Joanna Q.
Chlorine exists as two isotopes in nature, ${ }_{1}^{5} \mathrm{Cl}$ (atomic mass $34.969$ amu, abundance $75.77 \%$ ) and ${ }_{17}^{37} \mathrm{Cl}$ (atomic mass $36.966$ amu). (a) What is the percent abundance of the ${ }_{1}^{37} \mathrm{Cl}$ isotope? (b) Calculate the weighted average of the atomic mass of naturally occurring chlorine. (c) How many times more massive is ${ }_{1}^{37} \mathrm{Cl}$ than ${ }_{17}^{35} \mathrm{Cl} ?$
