Name the reaction which takes place when a slow neutron beam strikes ._(92)^(235)U nuclei. Write the nuclear reaction involved.

The compound unstabel nucleus ._(92)^(236)U often decays in accordance with the following reaction ._(92)^(236)U rarr ._(54)^(140)Xe +._(38)^(94)Sr + other particles During the reaction, the uranium nucleus ''fissions'' (splits) into the two smaller nuceli have higher nuclear binding energy per nucleon (although the lighter nuclei have lower total nuclear binding energies, because they contain fewer nucleons). Inside a nucleus, the nucleons (protonsa and neutrons)attract each other with a ''strong nuclear'' force. All neutrons exert approxiamtely the same strong nuclear force on each other. This force holds the nuclear are very close together at intranuclear distances. Which of the following graphs might represent the relationship between atomic number (i.e., ''atomic weight'') and the total binding energy of the nucleus, for nuclei heavier than ._(38)^(94)Sr ?

Calculate the number of neutrons in the remaining atoms after the emission of an alpha particle from ._(92)U^(238) atom.

Two other possible ways by which .^(235)U can undergo fission when bombarded with a neutron are (1) by the release of .^(140)Xe and .^(94)Sr as fission fragments and (2) by the release of .^(132)Sn and .^(101)Mo as fission fragments. In each case, neutrons are also released. Find the number of neutrons released in each of these events.
