 12) (a) 6632Ge

             Ge has 32 11p and 34 10n with a ratio of 34 10n/32 11p = 1.06:1. Because of the low ratio Ge undergoes positron (01e) emission.      

             

       (b) 10545Rh

             Rh has 45 11p and 60 10n with a ratio of 60 10n/4511p = 1.33:1. Because of the high ratio Rh undergoes beta (0-1e) emission.

 

       (c) iodine-137, 13753I

             I has 53 11p and 84 10n with a ratio of 84 10n/5311p = 1.58:1. Because of the high ratio iodine-137 undergoes beta (0-1e) emission.

 

       (d) cerium-133, 13358Ce

             Ce has 5811p and 75 10n with a ratio of 75 10n/5811p = 1.29:1. Because of the low ratio cerium-133 undergoes positron (01e) emission.
