Nuclear Fusion vs Fission (Lesson 4)

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• half-life
• gamma radiation

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

How do nuclear power-plants work?

• Fusion
• Half-life
• Fission
• Fusion or fission

Two nuclei with low masses are combined to form one nucleus of larger mass is called what?

• Nuclear fission

• Nuclear fusion

• Nuclear half-life

• Half-life

The product of nuclear fission includes

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

Complete the nuclear equation and determine the type of decay that is occurring in this reaction. 

• alpha
• beta
• gamma
• none

Where does fusion occur naturally?

• Underwater
• All around us
• In the radioactive waste
• On the sun

Which type of reaction does the diagram illustrate?

• Fission

• Fusion

• Alpha Decay

• Beta Decay

In a science class, Ava and Benjamin are discussing how the sun produces energy. They learn that two small nuclei combine into a larger nucleus through a process. What is the name of this process?

• fission

• fusion

• alpha decay

• beta decay

Olivia is learning about nuclear reactions in her science class. She comes across a process where a nucleus splits into smaller nuclei. What is this process called?

• fusion

• fission

• half-life

• gamma radiation
