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 J62 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 question for today, J62, is
a. Describe similarities between single covalent bonds, double covalent bonds, and triple covalent bonds. Use three (3) examples in your explanation. Be sure that you explain how each example demonstrates the concept being considered.
b. Describe differences between single covalent bonds, double covalent bonds, and triple covalent bonds. Use three (3) examples in your explanation. Be sure that you explain how each example demonstrates the concept being considered.
2. Do the problems 1, 2, 3, 4, and 6 on the first page of the worksheet packet on covalent bonding. Construct electron dot formulas single atoms of the elements shown in the initial state and then construct electron dot formulas that show all the valence electrons in single molecules of H2, F2, O2, N2, and HOH (skip CO2).
3.a. Use the PQ5R or SQ5R method to prepare study guide for text section 8.2 including subsections A B C D E F G on The Nature of Covalent Bonding or go to https://socratic.org/chemistry to research the topics brought up in section 8.2 of your text. Read section 8.2 in your chemistry text, pages 217 through 229, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and 1n the distributed handout packet. You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 8 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.
3.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 8.2 on page 220, read, analyze, and show your work for practice problems.
- Study Conceptual Problem 8.1 on page 220 and then do practice problem I8-8abc (In chapter 8, problem 1 parts a, b, and c), and then show your TE, VE, SE, NBE work for practice problems I8-8ab.
- After you are finished, check page R88 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 with that of your classmates when you come to class.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Take out the worksheet entitled “Property to be understood” distributed during study of ionic and metallic bonding.
- Fill in just the Covalent Network Solid column on the worksheet entitled “Property to be understood” using blue or black ink.
- In your Learning Log explain how the lack of electrical and thermal conductivity of covalent network solids is related to the localization of electrons in the atomic kernels and in the one, two, or three pairs of bonding pairs of negative electrons localized between each two positive nuclei or kernels of bonded nonmetal atoms.
- In your Learning Log explain how other properties of a covalent network solids are related to a model in which each two positive kernels of bonding nonmetal atoms within the three dimensional network of bonded atoms is held together by their attraction for the same one, two, or three bonding pairs of negative electrons located in the region between the positive charges.
- In your Learning Log record at least one question question you would want to ask your classmate or teacher about the above mentioned properties.
