Nuclear Science End-of-Unit Flashcard

Front

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?

Back

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

Gamma radiation is:

Back

High-energy electromagnetic waves emitted during radioactive decay.

Front

During a science research expo, Abigail presents a radioactive sample and explains that its half-life is the time it takes for what to happen?

Back

The time it takes for the sample to decay halfway.

Front

Explain nuclear energy to Lily.

Back

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

Front

What is a significant issue with the use of nuclear energy?

Back

Radioactive waste disposal.

Front

Why might radon levels be high in Grace's basement?

Back

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

Front

What is the difference between the processes of fission and fusion, which are responsible for energy sources like the Sun and nuclear reactors on Earth?

Back

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

Front

During a science fair, Sophia asked Rohan if the sun is on fire. How should Rohan respond?

Back

No, the sun is not on fire.

Front

How does the sun, a star, produce light?

Back

Through nuclear fusion of hydrogen atoms.

Front

How can hydrogen atoms release enough energy to power a city or create a destructive bomb?

Back

By undergoing nuclear fusion.
