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

Click all that apply to Fusion

• Generates more energy than fission

• generates less energy than fission

• requires high temperatures

• occurs in stars

Click all that apply to fusion...

• produces energy and helium (among other things)

• generates radioactive waste

• combines smaller nuclei to create a heavier nuclei

• occurs in nuclear reactors to produce electricity

Fission

• heavy nucleus breaks into lighter nuclei

• uses uranium

• does not create radioactive byproducts

• light nuclei combine to form a heavier nucleus

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 element is the main source of fuel for fusion?

• Uranium

• Hydrogen

• Carbon

• Krypton

Fission:

• Splitting of radioactive elements into lighter elements

• Combining of small elements into heavier elements

• Creates a LOT of energy

• Produces radioactive waste

U-235 is the primary fuel

• Fission
• Fusion
• Radioactive Decay
