Start the following in class:

Study for the summative assessment on chapter 5. 

1. Go to Pearson Chemistry Link To Chapter 5 Formative Assessment and take an online formative test for chapter 5, Electrons in Atoms. Then click on the Score My Test button and study anything that you do not yet understand.

2. Write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper. In the upper right corner white space of each upward facing page, write your hand in number within a circle followed by your name. Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each days paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.

The first required learning journal topic J44A for today is

a. What is meant by the term electron orbit?  

b. What is meant by the term electron orbital? 

c. Which concept is used in quantum mechanics, and why?

3. The second required learning journal topic J44B for today is

a. Which has more energy, an electron in the 1s orbital of a hydrogen atom or an electron in the 6s orbital of the same hydrogen atom? 

b. Explain your reasoning with the aid of at least one example.

Make sure that you use examples to clarify each idea that you express in your learning journal and make sure that you explain how each example demonstrates the concept being considered.

Recommended for those who have time left in their 45 minute study period, but not required of all:

1.  In preparation for your summative assessment on chapter 5 Electrons in Atoms, review and reinforce your command over certain important concepts.

  1. Review and study your notes, and your journal reflections. Study the Cornell notes that you took in and out of class. Review anything that you previously misunderstood on the Chapter 7 Study Guides, Chapter 7 Section Reviews, Chapter 7 Ionic and Metallic Bonding[Formative]Test A, and other work sheets which you now have checked using green ink. Look up anything that you still don’t understand in your text, glossary, vocabulary study sheets, class notes, or come to help class if you need help.
  2. Review the development of atomic theory according to the textbook’s authors and your teacher and take note of who hypothesized or discovered what and when.

    [Isaac Newton,

    John Dalton,

    Thomas Young,

    James Clerk Maxwell,

    J.J. Thomson,

    Hantaro Nagaoka,

    Albert Einstein,

    Ernest Rutherford,

    Niels Bohr,

    Otto Stern and Walter Gerlach,

    Louis DeBroglie,

    Clinton Davisson and Lester Germer,

    George Paget Thomson,

    Werner Heisenberg,

    Erwin Schroedinger,

    Wolfgang Pauli,

    Friedrich H. Hund,

    James Chadwick]

  3. Be able to draw logical conclusions from data (as the scientists listed above did).
  4. Note what Niels Bohr simple quantum theory stated about electrons in atoms and know how that differs from current quantum mechanical (or, wave mechanical) theory.
  5. Be able to use the formulas E = h · ν, or E = h· c
                                                                             λ

    to interconvert the energy of photon with the associated wave frequency or wavelength, or use  λ·ν = c to interconvert wave frequency, wavelength, and speed of light waves in a certain direction using SI units, given the values of Planck’s constant, h = 6.626 10 -34 J·s, and the speed of light in a vacuum, c = 2.998 10+8 m/s,

  6. Distinguish between the aufbau principle, the Pauli exclusion principle, and Hund’s rule.
  7. Be able to solve problems in which you are asked how many sublevels, orbitals, and total number of electrons are in various energy levels.
  8. Be able to identify orbitals of a given shape as s, p, d, or f orbitals and be able to write electron configurations for atoms with atomic numbers from 1 through 22.
  9. Review the meanings of the words on the chapter 1, chapter 2, chapter 3, chapter 4, and chapter 5 vocabulary lists. Place a – symbol in front of each word that you have to study more, and a change the – to a + symbol in front when you have demonstrated mastery over the word to a study buddy, parent, or friend.
  10. Distinguish pairs of chapter 5 vocabulary words that might be confused with each other.

    Do all the definitions reflect a thorough and correct understanding?

  11.  Study the Key Concepts given on pages 33, 57,95, 121, 148, 180, and 206 of the text.
  12. Study the SI prefixes and their mathematical meanings until you can readily explain the meaning of each listed SI prefix as a numerical multiplier.
