IPC: Chemical and Nuclear Reactions Review

Front

What happens during nuclear fission?

Back

A nucleus divides.

Front

What is the term for the time taken for half of an amount of radioactive atoms to decay?

Back

Half-life

Front

In a chemical reaction, if heat energy is absorbed, what does this indicate?

Back

The reaction is endothermic.

Front

What is a common use of radioactive materials in medicine?

Back

Tracers are used in medical imaging.

Front

What is a major drawback of nuclear fission reactors?

Back

The difficulty of achieving safe disposal of radioactive waste products.

Front

What is nuclear fusion?

Back

A process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

Define radioactive decay.

Back

The process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is the difference between nuclear fission and nuclear fusion?

Back

Fission splits a heavy nucleus, while fusion combines light nuclei.

Front

What is a common application of half-life in medicine?

Back

Determining the dosage of radioactive tracers.

Front

What type of reaction is characterized by the release of heat?

Back

Exothermic reaction.
