  • Mole
    S.I. base unit used to measure the amount of a substance whose number of particles is the same as the number of carbon in exactly 12g of carbon -12.
  • Avogadro's Number
    6.02 x 10^23, the number of atoms or molecules in 1 molecule.
  • Molar Mass
    Mass in grams of 1 molecule of a substance.
  • Electromagnetic Radiation
    Radiation associated with an electric and magnetic field; it varies periodically and travels at light speed.
  • Electromagnetic Spectrum
    All of the frequencies or wavelengths of electromagnetic radiation.
  • Wavelength
    Distance from any point on a wave to an identical point on the next wave.
  • Frequency
    Number of cycles or vibrations per unit of time; number of waves produced in a given amount of time.
  • Photoelectric Effect
    Emission of electrons from a material when light shines of certain frequencies shines on the surface of the material.
  • Quantum
    Basic unit of electromagnetic energy; it characterizes the wave properties of electrons.
  • Photon
    Unit of quantum of light; particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy.
  • Ground State
    Lowest energy state of a quantizied system.
  • Excited State
    State in which an atom has more energy that it does at its ground state.
  • Emission-line Spectrum
    Diagram or graph that indicates the degree to which a substance emits radiant energy with respect to wavelength.
  • Continuous Spectrum
    Uninterrupted broad band of all colors (wavelengths) emitted by incandescent solids.
  • Heisenberg Uncertainty Principle
    Principle that states that determining both the position and velocity of an electron or any other particle simultaneously is impossible.
  • Quantum Theory
    Study of the structure and behavior of the atom and of subatomic particles from the view that all energy comes in tiny, indivisible bundles.
  • Orbital
    Region in an atom where there is a high probability of finding electrons.
  • Quantum Numbers
    Number that specifies certain properties of electrons.
  • Principle Quantum Number
    Quantum number that indicates the energy and orbital of an electron in an atom.
  • Angular Momentum Quantum Number
    Quantum number that indicates the shape of an orbital.
  • Magnetic Quantum Number
    Quantum number that corresponds to the alignment of the angular momentum component with a magnetic field.
  • Spin Quantum Number
    Quantum number that describes the intrinsic angular momentum of a particle.
