Nuclear Chemistry level 2 practice

Front

What is a chain reaction in nuclear chemistry?

Back

A chain reaction is a process where a single nuclear reaction causes a series of subsequent reactions, typically seen in fission.

Front

What is fission?

Back

Fission is the process of splitting a large atomic nucleus into smaller nuclei, releasing energy and neutrons.

Front

What is fusion?

Back

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

Front

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay, represented as 0/-1 e.

Front

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation, not a particle, and is emitted from the nucleus during radioactive decay.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay where an atomic nucleus emits an alpha particle (2 protons and 2 neutrons), resulting in a new element.

Front

What is the role of neutrons in fission?

Back

Neutrons play a crucial role in fission by initiating the reaction when they collide with a large nucleus, causing it to split.

Front

What is the difference between fission and fusion?

Back

Fission involves splitting a heavy nucleus, while fusion involves combining light nuclei to form a heavier nucleus.

Front

What is the significance of nuclear reactions in energy production?

Back

Nuclear reactions, particularly fission, are significant in energy production as they release large amounts of energy used in nuclear power plants.

Front

What are the products of fission?

Back

The products of fission typically include smaller nuclei (fission fragments), neutrons, and a large amount of energy.
