ANSWER KEY Basics of Bonding & Lewis Dot Structures Part I. Summarizing Bond Types-Read the article “The Different Types of Bonds” and complete the table below using the following information: Forms between a Metal & Non - metal Outer electrons shells o verlap creating “sea of electrons” Forms large structures like: sugars, fats, You use double and triple bonds to show the sharing of electrons between atoms. You can find out when to use double and triple bonds in a Lewis structure by using bond math. The formula is: Number of bonds in a molecule = (number of octet electrons - number of valence electrons)/(2) An example: CO2 (24-16)/(2) = 4 bonds • (3c) ·Lewis dot diagrams are used to represent valence electrons in an element. Structural formulas show the arrangements of atoms and bonds in a molecule and are represented by Lewis dot structures. • Draw Lewis dot diagrams to represent valence electrons in elements and draw Lewis dot structures to show covalent bonding. EXAM PRACTICE REVIEW – 09 Lewis Dot Structures of Covalent Compounds (Single Bonds Only) – 01 General Information This assignment is not due. Use this assignment as review material for Exam 2. You will be able to use the periodic table (Appendix 0) for this assignment. Distribute to students copies of the Covalent Bonding Lewis Dot Structures Worksheets (S-C-4-1_Covalent Lewis Dot Structures.doc) and have students finish them in class. This worksheet can also be assigned as homework and handed in the next day. Refer to the answer key as necessary (S-C-4-1_Covalent Lewis Dot Structures KEY.doc). Part 3

Sonya Birazian 99,607 views Things to remember 1. Carbon (C) will always be the central atom and Hydrogen (H) will never be the central atom 2. In other cases choose the element that is the least electronegative (farthest to the left) on the periodic table. 3.

Sonya Birazian 99,607 views Dec 21, 2016 · The Lewis Dot Structure is a visual which represents the outermost shell of electrons, also known as valence electrons, and possible covalent bonds within an atom or molecule. These valence electrons are negatively charged and are attracted to the positively charged nucleus, made up of neutrons and protons. So, if I go ahead and show now three bonds between my two carbons, and then a hydrogen on either side, we can double check the octets on the carbon here, so I'll get out the magenta again, so two, four, six, and eight, so there is now an octet, and so this is the correct dot structure for ethyne or acetylene, and so we've seen how to draw ... It turns out, however, that both O–O bond distances are identical, 127.2 pm, which is shorter than a typical O–O single bond (148 pm) and longer than the O=O double bond in O 2 (120.7 pm). Equivalent Lewis dot structures, such as those of ozone, are called resonance structures.
