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 J48 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 question J48 for today is
a. Which has a smaller atomic size (atomic volume, atomic radius), an element farthest to the left or the element farthest to the right in a given period of the periodic table?
Use the concept of nuclear charge increasing as atomic number increases across a period to explain the trend in atomic size.
b. In your explanation, use data from Figure 6.19 on page 175 of the text and cite examples from group 2 and from group 6, for clarity’s sake. Make sure that you explain how each example demonstrates the concept being considered. [Check that the errors in the key or legend for Figure 6.19 on page 175 have been corrected: the label Metal ion should be Metal atom and the label Nonmetal ion should read Nonmetal atom.].
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.a. Go to https://socratic.org/chemistry to research the topics brought up in section 6.3 of your text, OR use the PQ5R or SQ5R method to prepare a study guide for section 6.3 of your chemistry text on Periodic Trends. Read section 6.3 in your chemistry text, pages 170 through 179, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. Or, if it will save you time, write a question for the section, read the section for the main idea and write a summary paragraph when you are done reading.
You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 6 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.
2. b. Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper in your learning log that hasn’t been written on. Place the page reference for the problems to be considered to the left of the red marginal line on the first blue line. Centered on the first blue line, write a descriptive title for the learning activity such as Section [chapter #.section#] Responses. Before you write your response to each question or problem listed below, write its designation to the left of the red marginal line as listed below, followed by your response in ink to the right of the marginal line.
- In the Section Assessment 6.3 on page 178, read, analyze, and show your work for practice problems I6-16 (In chapter 6, problem 16), I6-17, I6-18, I6-19, I6-20, I6-21, I6-22,and I6-23.
- After you are finished, check page R86 of the text and check each of those problems that you can by writing in either a check mark (√) or a correction in green ink as we do in class. Some questions do not have a suggested response given. For each such question, circle the number of the question in the margin of your notebook paper and check your response when you come to class.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Look for periodic trends in a property of single atoms of an element:
a. Plot (average) electronegativity of a single atom of an element vs. atomic number for element with atomic numbers 1 through 20 using LoggerPro. Let the vertical axis y be the electronegativity of an atom of the element from 0 to 4.0 and the horizontal axis be the atomic number from 1 through 20. Set the plotting program to use open circles as the symbol for each data point and to connect the points that you enter. To choose those settings in LoggerPro click inside the graph window and then go to the menu at the top of the screen and select Options > Graph Option > Appearance, and check the Point Symbols and Connect Points boxes if they have not already been checked. Look up the data on electronegativity using an interactive periodic chart.
b. Insert a text annotation onto your graph containing your first and last names, hand in number, and Honors Chemistry section number. In LoggerPro choose from the top menu Insert > Text or Insert Text Annotation and then place your cursor in the box and add your text.
c. Print off your chart and bring it to class, hole punch the paper, and put it with your class notes in your 3 ring binder.
