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, Xrays, 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
