Worksheet: Nuclear Fission and Fusion
In this worksheet, we will practice differentiating between nuclear fusion and fission reactions and writing balanced nuclear equations for both processes.
Which of the following statements is true?
- ABinding energy per nucleon decreases in nuclear fusion.
- BNuclear fission is endothermic.
- CNeutrons can be released in both nuclear fusion and nuclear fission.
- DNeutron bombardment is needed for nuclear fission to occur.
- EThe principal nuclear reaction in the sun involves emission.
Why is a high temperature required for nuclear fusion?
- AFusing nuclei must have enough kinetic energy to drive the conversion of protons to neutrons.
- BFusing nuclei must have enough kinetic energy to overcome the repulsion between their positive charges.
- CFusing nuclei must have enough kinetic energy to enter excited states before the collision.
- DThe kinetic energy of fusing nuclei must be greater than the increase in binding energy.
- EFusing nuclei must have enough kinetic energy to overcome the strong nuclear force between nucleons.
Nuclear fission is usually followed by a series of decays. How do these decays stabilize the smaller nuclei?
- AThe atomic mass increases.
- BThe nuclear charge increases.
- CThe neutron/proton ratio decreases.
- DThe atomic mass decreases.
- EThe proton/neutron ratio decreases.
In a nuclear reaction, an atom of collides with an atom of . Which of the following are not potential products of this reaction?
