Start the following in class:

Study for the summative assessment on chapter 6 that is to be given on your next school day that our class meets.  Today is day 51.  Study for your test which is scheduled for school day 52!  If your class does not meet on day 52, today’s home learning activities are listed under day 52 and on day 52 your home learning activities are those listed below.

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 J51 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 journal focus topic J51 for today is:

a. In a given period of the periodic table, which has a smaller attraction for electrons (ionization energy, electronegativity), an element farthest to the left or the element farthest to the right ? 

b. Use the concept of nuclear charge increasing as atomic number increases across a period to explain this trend.

c. Use data from Table 6.2 on page 177 of the text and cite examples from period 2 and from period 5 to show which elements in a given period have the smaller attraction for electrons.

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.  By doing that you can save time by not writing out the questions being asked.

2. a. Go to Pearson Chemistry Link To Chapter 6 Formative Assessment  and take an online formative assessment for chapter 6, The Periodic Table.  Then click on the Score My Test button and study anything that you do not yet understand.

b. Test your knowledge of periodic table trends: Do You Know the Trends in the Periodic Table?

3. Review important ideas associated with the periodic table in preparation for your summative assessment.

a. Review the discovery of the periodic relationships among the elements according to the textbooks authors and your teacher. Take note of what Johann W. Dobereiner, John Newlands, Dmitri Mendeleev, Lothar Meyer, and Henry Moseley discovered or hypothesized and when it was hypothesized or discovered.

b. Be able to draw logical conclusions from data (as those scientists mentioned above did).

c. Be able to estimate the value of an unknown property of a given element from an average of the values of the corresponding property for the elements above and below the given element on the period table.

d. Note what Dmitri Mendeleev stated as the periodic law, and know how that differs from the currently accepted formulation of the periodic law.

e. For the representative [s and p block] elements, know how properties such as atomic size, ionic size, relative attraction for electrons,nonmetallic character, and metallic character tend to change as one goes down a group.

f.  For the representative [s and p block] elements, know how properties such as atomic size, ionic size, relative attraction for electrons, nonmetallic character, and metallic character tend to change as one goes across a period.

g. Review anything that you previously corrected on the Chapter 6 Study Guides, Chapter 6 Section Reviews, Chapter 6 The Periodic Table [Formative]Test, and other work sheets which you now have checked using green ink.

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

h. Know the distinctions between pairs of chapter 6 vocabulary words that might be confused with each other.

i. Study the Cornell notes that you took in and out of class.

j. Look up anything that you still don’t understand in your text, glossary, vocabulary study sheets, class notes, or come to help class.
