Subatomic particles with a negative charge that orbit the nucleus of an atom.

Front

Electromagnetic Radiation

Back

Energy that travels through space in the form of waves.

Front

Wavelength

Back

The distance between successive crests of a wave.

Front

Frequency

Back

The number of waves that pass a given point per second.

Front

Front

Heisenberg Uncertainty Principle

Back

A principle stating that it is impossible to know both the position and momentum of a particle at the same time.

Front

Valence Electrons

Back

Electrons in the outermost shell of an atom that are involved in forming bonds.

Front

Octet Rule

Back

A chemical rule of thumb that reflects the tendency of atoms to prefer having eight electrons in their valence shell.

Front

Ions

Back

Atoms or molecules that have gained or lost one or more electrons, resulting in a net charge.

Front

Lewis Structures

Back

Diagrams that show the bonding between atoms and the lone pairs of electrons in a molecule.
