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. It includes the study of radioactivity, nuclear processes, and properties of radionuclides.

What is the half-life of a radioactive substance?

Back

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

If 10 mg of iodine-131 is given to a patient, how much is left after 24 days? (Half-life = 8 days)

Back

1.25 mg

What is the half-life of iodine-131?

Back

8 days

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus, resulting in the transformation of a neutron into a proton or vice versa.

Solve this equation for beta decay: 6^14C = ___ + -1^0e

Back

7^14N

What is a benefit of using nuclear power?

Back

Makes us less reliant on fossil fuels.

Front

What is the purpose of a Condenser in a Nuclear Power Plant?

Back

To cool exhaust steam from a turbine.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation into a different element or isotope.

Front

What are fission products?

Back

Fission products are the fragments left after a large nucleus splits into smaller nuclei during nuclear fission, often including a variety of radioactive isotopes.
