Nuclear Science End-of-Unit Quiz

Ethan and Benjamin are studying for their physics exam. Ethan says that alpha particles are positively charged, while beta particles are negatively charged. Benjamin disagrees. Ava, who is also studying with them, is asked to settle the dispute. What should Ava say?

• Ethan is correct, alpha particles are positively charged, while beta particles are negatively charged.

• Benjamin is correct, alpha particles are smaller in size than beta particles.

• Benjamin is correct, alpha particles are negatively charged, while beta particles are positively charged.

• Benjamin is correct, alpha particles are larger in size than beta particles.

During a science fair, David presents a project on different types of radiation. He explains that gamma radiation is:

• High-energy electromagnetic waves emitted during radioactive decay.

• Negatively charged particles emitted during radioactive decay.

• Positively charged particles emitted during radioactive decay.

• High-energy particles emitted during radioactive decay.

Oliver and Lily were learning about different types of energy in Science class, and their teacher mentioned nuclear energy. Lily was curious to know about it. How would you explain nuclear energy to Lily?

• It's the energy produced by the splitting of atoms.

• It's the energy produced by the decay of radioactive substances.

• It's the energy produced by the combustion of fossil fuels.

• It's the energy produced by the fusion of atoms.

Ava, William, and Evelyn are discussing the challenges of nuclear energy. They are trying to identify a potential problem with its use. What do they conclude as a significant issue?

• Radioactive waste disposal.

• High cost of production.

• Limited availability of resources.

• Environmental pollution.

Grace is concerned about the air quality in her basement. She learned that radon levels might be high due to which process?

• Radioactive decay of uranium and thorium in the soil beneath her home.

• Radioactive decay of carbon-14 in the atmosphere.

• Radioactive decay of oxygen in the air.

• Radioactive decay of hydrogen in water.

Aiden is learning about energy production in his science class. He is curious about the processes powering the Sun and nuclear reactors on Earth. What is the difference between the processes of fission and fusion, which are responsible for these energy sources?

• Fission releases energy, while fusion absorbs energy.

• Fission is the combining of atoms, while fusion is the splitting of atoms.

• Fission absorbs energy, while fusion releases energy.

• Fission is the splitting of atoms, while fusion is the combining of atoms.

At dinner last night, Michael explained to his parents how he learned that hydrogen atoms could release enough energy to power a city or create a destructive bomb. How is this possible?

• By absorbing gamma radiation.

• By undergoing nuclear fusion.

• By undergoing radioactive decay.

• By emitting alpha particles.
