Front

What is a chain reaction in nuclear chemistry?

Back

A continuous, self-feeding series of nuclear fission reactions.

Front

What is an alpha particle made of?

Back

2 protons and 2 neutrons.

Front

What does it mean when we say P-32 has a half-life of 14 days?

Back

After 14 days, 50% of the radioactive substance decays.

Front

Why is it difficult to carry out a fusion reaction in a nuclear reactor?

Back

It requires extremely high temperatures.

Front

If you start with 100 grams of iodine-131 and the half-life is 2 days, how many grams are left after 6 days?

Back

12.5 grams.

Front

Define nuclear fission.

Back

The process of splitting a heavy nucleus into smaller nuclei, releasing energy.

Front

What is nuclear fusion?

Back

The process of combining light nuclei to form a heavier nucleus, releasing energy.

Front

What is a radioactive isotope?

Back

An isotope that is unstable and decays over time, emitting radiation.

Front

What is half-life?

Back

The time required for half of a radioactive substance to decay.

Front

What are the three main types of radiation?

Back

Alpha particles, beta particles, and gamma rays.
