Introduction to Nuclear Chemistry

Front

*Front:* Atom

Back

The smallest particle of an element.

Front

*Front:* Alpha Particle

Back

Large, slow moving radiation particles that can be stopped by a piece of paper or skin.

Front

*Front:* Beta Particle

Back

Fast moving radiation (electrons).

Can be stopped by thin metal or protective clothing.

Front

*Front:* Gamma Ray

or

Gamma Radiation

Back

Very fast moving radiation.

Can only be stopped by lead or concrete.

Front

*Front:* Half-life

Back

The amount of time it takes for half of ta radioactive element to decay (become another type of element).

Front

*Front:* Fission

Back

Splitting of a nucleus into smaller fragments (parts).

Releases neutrons and a large amount of energy.

Front

*Front:* Fusion

Back

Reaction where two light nuclei combine to make one larger nucleus.

Releases a large amount of energy.

Front

*Front:* Chain Reaction

Back

A series of nuclear divisions (fission).

Front

*Front:* Isotopes

Back

An atom with a different number of neutrons than it would normally have (different from the most common form).

Front

*Front:* Neutron

Back

Neutrally charged subatomic particle located in the nucleus of an atom.
