What is Nuclear Physics?

Back

Nuclear Physics is the branch of physics that studies atomic nuclei, their interactions, and the fundamental forces that govern them.

Front

Define Radioactive Decay.

Back

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

What is Half-Life?

Back

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

Front

If a radioactive substance has a half-life of 16 days, how much of a 100g sample remains after 64 days?

Back

6.25g remains after 64 days.

What do control rods do in a nuclear reactor?

Back

Control rods regulate the rate of reaction by absorbing and slowing neutrons.

What is a neutron?

Back

A neutron is a subatomic particle found in the nucleus of an atom, with no electric charge.

Front

What is a positron?

Back

A positron is the antimatter counterpart of an electron, with the same mass but a positive charge.

Front

Explain the concept of nuclear fission.

Back

Nuclear fission is the process of splitting a heavy atomic nucleus into smaller nuclei, releasing a large amount of energy.
