    I am not getting the same answer in a nuclear decay problem

    Dawn Keckley

      My sons and I are working through a chemistry textbook.  We all three keep getting a different answer from the teacher guide.

       

      Gd 146/64 decays into e- and what? My sons and I keep getting Tb 146, but the teacher guide says Eu 146. Isn't this an example of beta decay, where a neutron becomes a proton?

       

      Thank you,
