Front

What is the definition of nuclear fission?

Back

A nuclear reaction in which a heavy nucleus splits into smaller nuclei, releasing energy.

Front

What is the definition of nuclear fusion?

Back

A nuclear reaction in which two light nuclei combine to form a heavier nucleus, releasing energy.

Front

What is half-life in nuclear chemistry?

Back

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

Front

What type of radiation is emitted during alpha decay?

Back

Alpha particles, which consist of 2 protons and 2 neutrons.

Front

What is the primary difference between fission and fusion?

Back

Fission splits heavy nuclei, while fusion combines light nuclei.
