Supply the missing atomic symbol to complete the equation for the following nuclear fission reaction.


1/0n +235/92U ------> 137/52 Te +?/?X + 2 1/0 n + energy

also how do you decipher whether its 2 1/0n rather than 3?

  • chem -

    The lower numbers must add to the same on both sides. The upper numbers must add to the same on both sides.

    On the bottom. You have 92 + 0 on the left. There must be 92 on the right. We have 52 + 0 showing; the remainder must be the lower number for X. Look on the periodic table to find that element.
    Top numbers are done the same way.
    235+1 on the left = 236.
    On the right, 236 - 137 -2 = top number for X.
