Nuclear Chemistry Review

Front

What is nuclear fusion?

Back

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

Front

What type of radiation emits an electron?

Back

Beta radiation.

Front

Which type of radiation has the greatest mass?

Back

Alpha radiation, which consists of two protons and two neutrons.

Front

What does the mass number of an element represent?

Back

The total number of protons and neutrons in the nucleus of an atom.

Front

Which form of radiation can be stopped by your skin or a piece of paper?

Back

Alpha radiation.

Front

What is nuclear fission?

Back

A process where a heavy nucleus splits into two lighter nuclei, accompanied by the release of energy.

Front

What is alpha decay?

Back

A type of radioactive decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons).

Front

What is beta decay?

Back

A type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus.

Front

What is gamma radiation?

Back

High-energy electromagnetic radiation emitted from a nucleus during radioactive decay.

Front

What is the difference between alpha, beta, and gamma radiation?

Back

Alpha radiation consists of heavy particles, beta radiation consists of electrons, and gamma radiation consists of high-energy photons.
