  1. Either you've made a typo or this is a screwed up question. 236/92 can't be Te. It MUST be U. And what is 2(1/2)n? neutrons are 1/0.

  2. 1/0 n + 235/92 U ---> 236/92 U ---> 137/52 Te + _____ +2 (1/2n)

    Sorry my mistake!!!

  4. I asked my instructor and he said he made a mistake with this question and it should be like this

    1/0 n + 235/92 U ---> 236/92 U ---> 137/52 Te + _____ +2 (1/0 n)

  5. ok Now we can do something.
    Make the top numbers add up and the bottom numbers add up.
    on the left.
    top...1 + 235 = 236
    bottom 0 + 92 = 92 which does nothing more than show that 236/92U is right.
    Now to the next part of the reaction.
    top: 236 = 137 + ? + (2*1) and solve for ?. I get 236-137-2 = 97
    bottom: 92 = 52 + ? + 2*0 and solve for ?. I get 92-52-0 = 40
    So the top number is 97 and the lower number is 40. The lower number of 40 is the atomic number; look on the periodic table and find element #40. Is that Zr? So now the full equation (just that part of it) is
    236/92 U ==> 137/52 Te + 97/40 Zr + 2(1/0n)
