A scientist studying the reaction above is surprised to find traces of Xe-124 in their analysis of the reaction. How is Xe-124 different from Xe-135?

Answer :

Xe-124 different from Xe-135, because Xe-135 is a more massive isotope than Xe-124.

Isotopes of xenon, not ions, make up Xe-135 and Xe-124. Ions have charges, whereas isotopes of a given element have different numbers of atomic nuclei; as a result, Xe-135 is a more heavy and massive isotope of xenon than Xe-124.

Note that only the neutron number can account for this change in mass. The identification of the element would change if the proton number changed. A mismatch in charge would result from changing the amount of electrons without changing the mass.
