This is the only set of products of the four that satisfies the conditions that the atomic numbers add to 92 and the atomic mass numbers add to 234, (allowing for two neutrons to make up the total of 236).

When a nucleus undergoes fission, the two daughter nuclei are generally radioactive. By which process are they most likely to decay? 1 2 3 33% 33% 33% 1 2 3 4 5 1. alpha decay 2. beta decay (e ) 3. beta decay (e + )

According to Figure 44.4, the ratio N / Z increases with increasing Z . As a result, when a heavy nucleus fissions to two lighter nuclei, the lighter nuclei tend to have too many neutrons for the nucleus to be stable. Beta decay in which electrons are ejected decreases the number of neutrons and increases the number of protons in order to stabilize the nucleus.
