Term
|
Definition
| the height of a wave's crest. |
|
|
Term
|
Definition
| the pattern formed when light passes through a prism or diffraction grating to separate it into the different frequencies of light it contains. |
|
|
Term
|
Definition
| a mathematical expression describing the probability of finding an electron at various locations; usually represented by the region of space around the nucleus where there is a high probability of finding an electron. |
|
|
Term
|
Definition
| the rule that electrons occupy the orbitals of lowest energy level first. |
|
|
Term
| electromagnetic radiation |
|
Definition
| energy waves that traveil at a speed of approximately 300 million meters per second in a vaccuum; includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays,, and gamma rays. |
|
|
Term
|
Definition
| the arrangement of electrons of an atom in its ground state into various orbitals around the nuclei of atoms. |
|
|
Term
|
Definition
| the specific energies an electron in an atom can have. |
|
|
Term
|
Definition
| the number of wave cylces that pass a given point per unit of time; frequency and wavelength are inversely proportional to each other. |
|
|
Term
|
Definition
| the lowest possible energy of an electron as described by quantum mechanics. |
|
|
Term
| Heisenberg Uncertainty Principle |
|
Definition
| it is impossible to know exactly both the velocity and the position of a very small particle at the same time. |
|
|
Term
|
Definition
| the unit of frequency, equal to one cylcle per second. |
|
|
Term
|
Definition
| electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible. |
|
|
Term
| Pauli Exclusion Principle |
|
Definition
| an atomic orbital may describe at most two electrons, each with opposite spin direction; it is impossible for any two electrons within an atom to have all four of their quantum numbers to be identical. |
|
|
Term
|
Definition
| a quantum of light or a discrete bundle of electromagnetic energy that interacts with matter in a similar manner as particles. |
|
|
Term
|
Definition
| the amount of energy necessary to move an electron from one energy level to another. |
|
|
Term
|
Definition
| the primarily mathematical, modern description of the behavior of electrons in atoms |
|
|
Term
|
Definition
| wavelengths of visible light that are separated when a beam of light passes through a prism; range of wavelengths of electromagnetic radiation. |
|
|
Term
|
Definition
| the distance between adjacent crests of a wave. |
