Start the following in class:

1. 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 required focus journal questions J50A for today are .

a. Which has a smaller attraction for electrons (ionization energy, electronegativity), an element at the top of a group or an element at the bottom of the same group on the periodic table?  Use an example to clarify the idea that you express in your learning journal and explain how each example demonstrates the concept being considered.

b. Use the concept of an increasing distance of the highest occupied energy level (valence electron shell) from the nucleus to explain this trend. In your explanation, 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) for clarity’s sake. 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. and b. 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 all the pages in the chapter 6 The Periodic Table[Formative] Test as a formative assessment to find out some of the things that you do and do not know, and not as a research project.

  • If you did not obtain a section review packet for the chapter in class, go to MNSD Google Drive > Student Resources > Formative Tests and print off a copy of the test for the chapter you are studying.  Each chapter test is identified by a name whose last two digits is the chapter number.  When you open the chapter formative test the first page will have the words “Chapter Test A” in the title.
  • For each question or problem challenge, either answer the question to the best of your ability using one or more full sentences, or answer the problem to the best of your ability by recording any numbers and units together with the mathematical operations performed in symbolic terms, along with the solution to the problem which should be circled.
  • This is an important assignment. Each formative test is a real chapter test that some teachers in other schools might use as a chapter test, so after taking the test, make sure that you understand each unfamiliar word, idea, concept, and problem.  Be sure to finish this packet in its entirety.
  • After doing the formative test, 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.    In that way make sure that you understand each idea that you originally did not have a complete understanding of.  Then you will be able to study more efficiently by studying that which you corrected in green ink.

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

1. Use the handout entitled The Periodic Table & Periodic Trends to complete and study your informational handout on periodicity, atomic size, metallic character, characteristics of metals.  Assign names to periodic groups, and indicate periodic trends in properties across periods of the s and p block elements and periodic trends down groups in the s and p blocks on small the periodic chart diagrams provided in the handout.  Specifically,

  • On one of the mini periodic charts of representative elements toward the back of the handout, use the terms, increases, decreases, or stays constant together with a directional arrows to label the periodic trends in atomic radii as one goes across periods of the representative elements, and as one goes down groups belonging to the representative elements.
  • On one of the mini periodic charts of representative elements toward the back of the handout, use the terms, increases, decreases, or stays constant together with a directional arrows to label the periodic trends in ionic radii as one goes across periods of the representative elements, and as one goes down groups belonging to the representative elements.
  • On one of the mini periodic charts of representative elements toward the back of the handout, use the terms, increases, decreases, or stays constant together with a directional arrows to label the periodic trends in the relative attraction for electrons as one goes across periods of the representative elements, and as one goes down groups belonging to the representative elements.
  • On one of the mini periodic charts of representative elements toward the back of the handout, use the terms, increases, decreases, or stays constant together with a directional arrows to label the periodic trends in nonmetallic character as one goes across periods of the representative elements, and as one goes down groups belonging to the representative elements.

2. For your second journal entry, J50B, on your three holed 8.5 inch by 11 inch ruled paper, you are to construct a concept map. .For your next journal entry on your three holed 8.5 inch by 11 inch ruled paper, you are to construct a concept map.  Please turn to page 180 in your text and construct a concept map relating at least the seven terms listed at the bottom of the page as today’s second journal reflection.  Draw verb phrase labeled arrows from the subject word to the object word being mapped such that a true sentence reads in the direction of the arrow. That is, you need to draw a labeled arrow from each subject word to the object word to which it is related. Express the relationship between the two words by writing a sentence using the two words. Think of a verb or verb phrase that relates each subject word at the tail of the arrow to the object or predicate nominative word at the head of the arrow. Write the verb phrase that relates the two words as a meaningful sentence next to the middle of each arrow that connects the two words.

3.  Download the flipchart on periodicity after clicking on the following link: PeriodicityClick through the chart quickly and take Cornell notes on concepts that you were unaware ofAt the end of your study, write a summary statement of what you learned.
