|
Amplitude
|
The height of a wave's crest
|
|
|
Atomic Emission Spectrum
|
The pattern formed when light passes through a prism or diffreaction grating to separate it into the different frequencies of light it contains
|
|
|
Atomic Orbital
|
A mathematical expression describing the probability of finding a electron at various locations; usually represented by the region of space around thte nucleus when there is a high probability of finding an electron
|
|
|
Aufbau Principle
|
The rule that electrons occupy the orbitals of lowest
energy first |
|
|
Electromagnetic Radiaiton
|
Energy waves that travel in a vacuum at a speed of 2.998 x 10 m/s; includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays
|
|
|
Electron configurations
|
The arrangement of electrons of an atom in its ground state into various orbitals around the nuclei of atoms
|
|
|
Energy Levels
|
The specific energies an electron in an atom or other system can have
|
|
|
Frequency
|
The number of wave cycles that pass a given point per unit of time; frequency and wavelength are inversely proportional to each other.
|
|
|
Ground State
|
The lowest possible energy of an electron described by quantum mechanics
|
|
|
Heisenberg Uncertainty Principle
|
It is impossible to know exactly both the velocity and the position of a particle at the same time
|
|
|
Hertz
|
The unit of frequency, equal to one cycle per second
|
|
|
Hund's rule
|
The electrons occupy orbitals of the same energy in a way that makes the number or electrons with the same spin direction as large as possible
|
|
|
Pauli Exclusion Principle
|
An atomic orbital may describe at most two electrons, each with opposite spin direction
|
|
|
Photons
|
A quantum of light; a discrete bundle of electromagnetic energy that interacts with matter similarity to particles
|
|
|
Quantum
|
The amount of energy needed to move an electron from one energy level to another
|
|
|
Quantum Mechanical Model
|
The modern description, primarily mathematical, of the behavior of electrons in atoms
|
|
|
Spectrum
|
Wavelengths of visible light that are separated when a beam of light passes through a prism; range of wavelength of electromagnetic radiation
|
|
|
Wavelength
|
The distance between adjacent crests of a wave
|
|
|
siempre
|
always
|
|
|
nunca
|
never
|
|
|
tambien
|
also, too
|
|
|
tampoco
|
neither, either
|
