Problem

a. (i) Calculate the neutron number

N

and the

N/Z

ratio for the nuclide

_{53}^{131}\mathrm I

. b. (ii) Based on this ratio, predict whether the nucleus is more likely to undergo

\beta^{-}

decay or

\beta^{+}

decay to reach greater stability. c. (iii) Write the balanced nuclear equation for the predicted decay.
