Sketch, on paper, the Lewis structure of O2, 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 O2? 12 What type of bond exists between the two oxygen atoms? Double How many lone pairs are there on each oxygen atom? 2多重下拉选择题
