The shortest distance between equivalent points on a continuous wave; is usually expressed in meters, centimeters, or nanometers.
|
Wavelength
|
|
the number of waves that pass a given point per second
|
Frequency
|
|
includes all forms of electromagnetic radiation, with the only differences in the types of radiation being their frequencies and wavelengths.
|
Electromagnetic spectrum
|
|
a phenomenon in which photoelectrons are emitted from a metal surface when light of a certain frequency shines on the surface.
|
Photoelectric effect
|
|
the lowest allowable energy state of an atom
|
Ground state
|
|
the electrons in an atoms outermost orbital’s; determine the chemical properties of an element.
|
Valence electron
|
|
a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs.
|
Lewis dot structure
|
|
an extremely unreactive group 8A element.
|
Noble gas electron
|
|
states that single electrons with the same spin must occupy each equal-energy orbital before additional electrons with opposite spins can occupy the same orbitals.
|
Hund’s rule
|
|
states that a maximum of two electrons may occupy a single atomic orbital, but only if the electrons have opposite spins.
|
Pauli exclusion principle
