Front

What is Positron Emission?

Back

A type of radioactive decay in which a positron (the antimatter counterpart of an electron) is emitted from an atomic nucleus.

Front

What is the mass of gamma rays?

Back

Gamma rays have no mass.

Front

What is a common concern regarding nuclear power plants?

Back

The threat of a nuclear accident or spill.

Front

What is a chain reaction in nuclear chemistry?

Back

When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, causing them to split.

Front

What is the half-life of iodine-131?

Back

8 days.

Front

Define Alpha Decay.

Back

A type of radioactive decay where an atomic nucleus emits an alpha particle (2 protons and 2 neutrons).

Front

Define Beta Emission.

Back

A type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus.

Front

What is Beta Capture?

Back

A process in which an atomic nucleus captures an electron, leading to a decrease in atomic number.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a heavy nucleus into smaller nuclei, while fusion is the combining of light nuclei to form a heavier nucleus.

Front

What are the uses of nuclear chemistry?

Back

Nuclear chemistry is used in medicine (radiotherapy), energy production (nuclear power), and in scientific research.
