  • Front
  • Back
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
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
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
A quantum of light; a discrete bundle of electromagnetic energy that interacts with matter similarity to particles
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
Wavelengths of visible light that are separated when a beam of light passes through a prism; range of wavelength of electromagnetic radiation
The distance between adjacent crests of a wave
also, too
neither, either
