Mass defect, Binding energy, Nuclear Fission & Fusion

_________ happens naturally due to an unstable nucleus.

• fission
• fusion
• radioactive decay
• K-capture

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• decay
• gamma radiation

What is a chain reaction?

• When electrons 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

An example of an uncontrolled fission reaction is _______________

• Nuclear power plants
• Radio active decay
• Atomic Bomb
• On the surface of the sun

This is an example of...

• Fission  reaction
• Fusion reaction
• Decomposition reaction
• Decay

The product of nuclear fission includes

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

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

• Nuclear fission
• Nuclear fussion
• Nuclear half-life
• Half-life

Which of the following is true about nuclear fusion?

• It is easy to implement.
• It produces less energy than nuclear fission.
• It produces more energy than nuclear fission.
• It has the ability to occur easily in everyday life.

What is true about nuclear fusion? 

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

Nuclear binding energy is

• the energy required to overcome the electrostatic force between the protons in the nucleus

• energy equivalent of the mass of the protons in the nucleus

• the energy equivalent of the mass of all the nucleons in the nucleus

• the energy equivalent of the difference between the total mass of the individual nucleons and their mass when they are contained in the nucleus
