Question 15

An isotope of chlorine, 1735Cl^{35}_{17}\text{Cl}1735​Cl, exists as a bare nucleus, while another isotope, 1737Cl^{37}_{17}\text{Cl}1737​Cl, exists as a singly-charged positive ion, 1737Cl+^{37}_{17}\text{Cl}^{+}1737​Cl+.

What is the ratio:

specific charge of the 1735Cl nucleusspecific charge of the 1737Cl+ ion \frac{\text{specific charge of the }^{35}_{17}\text{Cl}\text{ nucleus}}{\text{specific charge of the }^{37}_{17}\text{Cl}^{+}\text{ ion}} specific charge of the 1737​Cl+ ionspecific charge of the 1735​Cl nucleus​

(Assume the mass of each species is represented by its nucleon number multiplied by the atomic mass unit uuu.)

A
