Chem Comm ~ Fission / Fusion

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• half-life
• gamma radiation

The product of nuclear fission includes

• neutrons and electrons
• several nuclei and neutrons
• several nuclei and electrons
• several nuclei and protons

Which of the following is true about nuclear fission?

• The mass of the product is greater than the mass of the original nucleus
• The mass of the product is less than that of the original nucleus
• The mass of the product is the same as the mass of the original nucleus
• The mass of the product is 100 times greater than the original nucleus

What is a chain reaction?

• When electrons travel are emitted causing electricity
• When a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split

What is a beneficial aspect of nuclear fission?

• The ability to absorb energy
• The ability to release tremendous amounts of energy
• The ability to produce more energy than nuclear fusion
• There are no beneficial aspects of nuclear fission
