Terms in this set (38)
Measured in Hz; variable is v a.k.a. nu; number of waves that pass a point after a certain period of time
Measured in meters; variable is an upside-down y; length of one complete wave
Radio waves- microwaves- infrared- visible light- ultraviolet rays- x-rays- gamma rays
Visible light spectrum
Violet- indigo- blue- green- yellow- orange- red
Equation: speed of light (m/s)=wavelength (m) times frequency (Hz)
Wave particle duality
Light and electrons are both waves and particles
When an atom absorbs energy, electrons move ___ energy levels
When an atom releases energy, electrons move ___ energy levels
Particle (and wave) that is released and gives off light and color when electrons move down energy levels
Quantum of energy
Amount of energy needed for electrons to switch levels
Equation: energy (J)=Planck's constant (J times s) times frequency (Hz)
Derived equation: use when you are given wavelength and need to find energy. Energy [J]=(Planck's constant [J times s] times speed of light [m/s]) / wavelength [m]
Line emission spectra
A specific element's visible light spectrum; unique for each element
region in space with 90% probability of finding an electron; contains a maximum of two electrons with opposite spins
An electron's "address"; have four parts
Energy level (quantum)
The level of energy. First number in quantum number. Symbol is n.
The orbital type, or sub level, in it's numerical representation. Second number in quantum number. Symbol is l.
The orbital within a sublevel the electron is in. Third number in quantum number. Symbol is m (subscript l).
Electron spin quantum
An electrons' spin. Fourth number in quantum number. Symbol is s.
Sphere shaped. Contains one orbital.
Propeller shaped. Contains three orbitals.
Daisy shaped. Contains five orbitals.
Funky! Contains 7 orbitals.
Notation with labeled boxes and arrows representing spins.
Normal, long hand notation for electron location
Simplified electron configuration notation; start with a noble gas
Pauli's Exclusion Principle
Orbitals contain two electrons with opposite spins, and no two electrons in one atom may have the same four quantum numbers
The "urinal" rule: electrons will take an orbital individually within a sub level before sharing an orbital
Electrons will fill the lowest energy ORBITALS first
An electron is ___ if it has a full energy level, a full sublevel, or a half-full sublevel.
Copper and chromium
___ and ___ are two elements that stabilize automatically.
Positive ions lose electrons from the HIGHEST ___ ___ because the electrons there use less energy to get rid of.
Term for negative ion
Term for positive ion
Elements or ions with the same electron configuration
These certain elements have full energy levels.
The greater the size of an energy level, the ___ the energy.
Heisenberg Uncertainty Principle
It is impossible to find the position and velocity of a particle at once
