Unit 9 Test Review
  • The test will consist of 25 multiple choice questions. Please bring a calculator and a #2 pencil.
  • Formulas and constants will be provided. A periodic table will be provided.
  • Identify and apply the quantum numbers
  • Principal quantum number – 7 main energy levels…
  • Orbital quantum number – shape of area where electron travels
    • s – sphere
    • p – peanut
    • d – double peanut
    • f – flower
  • Magnetic quantum number – gives orientation of shape
    • s - 1 orbital, 2 electrons
    • p - 3 orbitals, 6 electrons
    • d - 5 orbitals, 10 electrons
    • f - (7 orbitals, 14 electrons)
  • Spin quantum number – clockwise and counterclockwise
  • Main energy sublevels:
    • Energy level 1 – s
    • Energy level 2 – s and p
    • Energy level 3 – s, p, and d
    • Energy level 4-7 – s, p, d, f
  • Aufbau principle – electrons enter lowest energy level first
  • Pauli exclusion principle – no 2 electrons within an atom can have the same 4 quantum numbers; 2 electrons within an orbital must have opposite spin numbers
  • Hund’s rule – electrons will fill each orbital singularly… and then fill the orbitals completely…(movie theater rule)
  • Compare and contrast the quantum mechanical model to the Bohr and previous models
  • Write and read ground state electron configurations
  • Write and read shorthand electron configurations
  • Determine the number of valence electrons from a given electron configuration
  • Read and write proper orbital notations
  • Differentiate between the types of electromagnetic radiation
  • Demonstrate understanding of wave mechanics model
  • Explain the concept of light…how is it emitted???
  • Complete calculations that involve wavelength, frequency, and the speed of light
  • Complete calculations that involve energy, frequency, and Planck\'s constant
  • Apply the concept of valence electrons to Lewis dot structures, electron configuration, and orbital notation
  • Differentiate between proper Lewis dot structures
  • Define and apply the periodic trends:
    • Atomic radii
    • Electronegativity
    • First Ionization energy
    • Metallic character
  • In order to be successful during this test, we highly recommend that you know how to read and use the periodic table
