Question

When a 235 92U nucleus is bombarded by neutrons (10n) it undergoes a fission reaction, resulting in the formation of two new nuclei and neutrons. The following equation is an example of one such fission process:

235 92U+10nAZBa+9436Kr+310n

Enter the isotope symbol for the barium (Ba) nucleus in this reaction.

In another process in which 235 92U undergoes neutron bombardment, the following reaction occurs:

235 92U+10nAZSr+143 54Xe+310n

Enter the isotope symbol for the strontium (Sr) nucleus in this reaction.

Explanation / Answer

92U235+0n156B139a+36Kr94+30n1

92U235+0n138Sr90+ 54Xe143+30n1
