does this equal Cadmium or Mercury? 'Chemistry An Atoms Based Approach' problem 2.97 (c) says the answer is Hg mass number 110
I came up with Cadmium is this a typo?

¹⁰⁸Ag is radioactive (half-life 2.39 min), which beta decays to ¹⁰⁸Cd.

If ¹⁰⁸Ag absorbs a neutron, it would become ¹⁰⁹Ag, and there should be a spontaneous emission of a prompt gamma. ¹⁰⁹Ag is a stable isotope.

¹⁰⁹Cd is unstable and decays by electron capture to ¹⁰⁹Ag.

Ag has Z=47, Cd has Z=48, and In has Z=49. Hg has Z = 80, while Au has Z=79. Au has only one stable isotope, ¹⁹⁷Au, which when absorbing a neutron becomes ¹⁹⁸Au, which decays by beta decay to a stable nuclide ¹⁹⁸Hg. In beta decay, a neutron transforms to a proton, electron and antineutrino.

There is no Hg mass number 110. There is ¹⁹⁰Hg, which has Z = 80 (80 protons) and N = 110 (110 neutrons), and it is unstable/radioactive with a half-life of 20 min.
