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
