Quantum Theory of the Atom
Wave particle duality of light
Characteristics of waves
Frequency, wavelength, and amplitude . YOU NEED TO DEFINE EACH
The electromagnetic spectrum
Range of frequencies of electromagnetic radiation and their wavelengths and photon energies. There are line spectrums. The specific colors of elements line up on their scale. WHY ARE THEY PRODUCED?
WHAT ABOUT A CONTINUOUS SPECTRUM?
The mathematical relationship between wavelength and Frequency
Speed of light= wavelength*frequency . They are inversely proportional.
Planck's Constant
6.626 x 10^-34 J*s, Planck proposed that energy emitted by hot objects was quantized.
WHAT DO YOU USE THIS CONSTANT FOR?
Photoelectric effect
the emission from a metal's surface when light of a certain frequency, or higher, shines on a surface
HOW DO YOU CALCULATE THE ENERGY OF A PHOTON?
Quantum Mechanical Model
The quantum mechanical model
Uses complex shapes of orbitals called electron clouds in volumes of space in which there is likely to be an electron.
Atomic Emission Spectrum
Atomic emission spectra are unique spectra of light emitted by an element when electricity is run through it or when it is viewed through a prism. Because they are unique, they can act as an element s fingerprint.
Quantum
The minimum amount of energy that can be gained or lost.
Orbitals
Probability of where the electrons are likely to be surrounding the nucleus
PRINCIPAL QUANTUM NUMBER, ENERGY LEVELS, SUBLEVELS???
Electron Configuration
Heisenberg's uncertainty principle
The more exact the position of the electron is determined, the less precisely its velocity can be known
Pauli's Exclusion Principle
no two e- can have the same four quantum numbers
The Aufbau principle:
In the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
Hund's rule and their relationship to electron location
Level
Sublevel
Orbital
every orbital must have one e- before any one orbital can have two
YOU NEED TO DEFINE ALL THESE
WHAT ABOUT THESE?
Lewis diagrams
VISUAL representation of the atoms valence electrons.
