Question
What will happen if slow moving neutrons are made to strike the atoms of a heavy element `''235_92U`? What is the name of this process?
Solution
When the atoms of a heavy element, U-235, are bombarded with slow-moving neutrons, the uranium nucleus breaks up to produce two medium-weight atoms, barium-139 and krypton-94, with the emission of three neutrons. A tremendous amount of energy is produced in this process. The name of this process is nuclear fission.
