Start the following in class:

1.   In your Journal Notebook 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, use a blue or black pen to write your hand in number within a circle followed by your name.
  • To the left of the marginal line, print J49 and circle it.
  • 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 day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.

The required focus journal question J49 for today is .

a.  Which has a larger atomic size (atomic volume, atomic radius), an element at the top of a group or an element at the bottom of the same group on the periodic table? 

b. Use data from Figure 6.19 on page 175 of the text and cite examples from group 1 (1A) (the alkali metals) and from group 17 (7A) (the halogens) to justify why you answered question a in the way you did.

c. Explain the trend in atomic size as one considers atoms of elements of increasing atomic number in the same group of elements. Use the concept of an increasing distance of the highest occupied energy level (valence electron shell) from the nucleus in your explanation.  Use an example to clarify the idea that you express in your learning journal and explain how each example demonstrates the concept being considered.

Note: Please label your responses to the questions correctly (a., b., and c. in the above example) and phrase your response to include enough information so that people reading your response can understand the question being answered.  That way you can save time by not writing out the questions being asked.

2.  Do the Chapter 6 Section Reviews handout as a formative assessment, and by not looking up answers, make it possible to find out what you do and do not  understand when the suggested responses key is later checked in class.  Do not skip any question, nor any part of a question.

[For each question or problem challenge, to the best of your ability either record your response to the question using one or more full sentences, or record your response to the problem.   For a problem, record any numbers and units together with the mathematical operations performed in symbolic terms, along with the solution to the problem, which should be circled.]

  • After doing the section review packet, but before you demonstrate your understanding on our class’ chapter test, you will check all your responses using green ink check marks √ for each correct response, and by lining out (striking trough) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way.   Then, when you know what you didn’t understand, you will be able to study more efficiently by studying that which you corrected in green ink.
  • If you are not sure of the correctness of your response, write down what you evaluate to be the difficulty and ask about it in class at the proper time.  If necessary, arrange to get help.

3. Take Cornell notes on the first 5 pages of the informational handout on periodicity, The Periodic Table & Periodic Trends, fill in the family names of the periodic groups on page 6, and then study your notes.

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

1. Review and reinforce your command over certain important concepts.

  1. Review the meanings of the words on the chapter 1, chapter 2, chapter 3, chapter 4, chapter 5, and chapter 6 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.
  2. Check out the student made Quizlet for chapter 6 at https://quizlet.com/168598512/ch-6-the-periodic-table-flash-cards/.  Do all the definitions reflect a thorough and correct understanding?
  3. Study the Key Concepts given on page 33, page 57, page 95, page 121, page 148, and page 180 of the text.
  4. Turn to page 180 and read and study the chapter 6 Study Guide.
