Front

What are radioactive isotopes?

Back

Radioactive isotopes have very unstable nuclei.

Front

What type of reaction involves two lighter nuclei combining to form one heavier nucleus?

Back

Nuclear fusion.

Front

How do nuclear fusion reactions differ from nuclear fission reactions?

Back

Nuclear fusion reactions form heavier isotopes from lighter isotopes.

Front

Which radioactive isotope is commonly used to generate energy in nuclear reactors?

Back

Uranium-235.

Front

What caused the Fukushima Disaster?

Back

An earthquake that caused a tsunami.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy nucleus into two lighter nuclei.

Front

What is the primary product of nuclear fusion?

Back

Energy and heavier isotopes.

Front

What safety measures are important in nuclear power plants?

Back

Containment structures, cooling systems, and emergency protocols.

Front

What is half-life in nuclear chemistry?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay.

Front

What is the difference between alpha, beta, and gamma radiation?

Back

Alpha radiation consists of helium nuclei, beta radiation consists of electrons or positrons, and gamma radiation consists of high-energy photons.
