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 first 


Term
Electromagnetic Radiation ("EMR") 

Definition
energy waves that travel in a vacuum at a speed of 2.998 X 10^{8}m/s; includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, Xrays, and gamma rayst 


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 or other system can have 


Term

Definition
the number of wave cycles that pass a given point per unit of time; frequency and wavelength are inversely proportional to each othert 


Term

Definition
the lowest possible energy of an atom described by quantum mechanics 


Term
Heisenberg Uncertainty Principle 

Definition
it is impossible to know exactly both the velocity and the position of a particle at the same time 


Term

Definition
the unit of frequency, equal to one cycle per secondt 


Term

Definition
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 


Term
Pauli Exclusion Principle 

Definition
an atomic orbital may describe at most two electrons, each with opposite spin direction 


Term

Definition
a quantum of light; a discrete bundle of electromagnetic energy that interacts with matter similarly to particles 


Term

Definition
the amount of energy needed to move an electron from one energy level to another 


Term

Definition
the modern description, primarily mathematical, 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
