What is nuclear chemistry?

Back

Nuclear chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the nucleus.

What is a half-life?

Back

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

Front

How do you calculate the number of half-lives that have passed?

Back

Divide the initial mass of the substance by the remaining mass and then take the logarithm base 2 of that number.

Front

What is radioactive decay?

Back

Radioactive decay is the spontaneous breakdown of an unstable atomic nucleus, resulting in the release of energy and matter.

Front

What is fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What is fusion?

Back

Fusion is a nuclear reaction where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is the difference between fission and fusion?

Back

Fission splits heavy nuclei into smaller ones, while fusion combines light nuclei to form a heavier one.

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of 2 protons and 2 neutrons.

Front

What is a nuclear power plant?

Back

A nuclear power plant is a facility that uses nuclear reactions to generate electricity.
