Sketch, on paper, the Lewis structure of HCl, remembering to: Step 1: Arrange the atoms Step 2: Count the number of valence electrons. Step 3: Allocate two electrons between each pair of atoms which are assumed to be covalently bound. Step 4: Use the remaining valence electrons to form lone pairs, and/or double and triple bonds. What is the total number of valence electrons in HCl? 8 How many electrons are shared between hydrogen and chlorine? 2 How many lone pairs are there on the chlorine atom? 3  多重下拉选择题
