40 Unit 1:Matter and Qualitative Analysis Part C: Compounds Assignment 11: Lewis Structures for Molecular Compounds 1. Draw the Lewis symbols for each element in the compound, Note, if the formula is H2O. forexample, you will need to draw 2H atoms and 10 atom. 2. Note the number of single electrons in the Lewis symbol. That's how many bonds the elementcan make, and needs to make to form a stable outer shell. a. If the number of single electrons is the same, pair up the single electrons between the two elements to create bonds. b. If the number of single electrons is different, put the element with the most single electrons in the middle, and the one with the fewer single electrons surrounding it c. Replace each pair of single electrons with a stick bond H2 F2 02 N HCI HBr HO H2S NH, Wh NC13 CHA CCIA Sino rhind
