All right. So that's how to use VSEPR to predict the shape. Let's do another example. So CO2-- so carbon dioxide. So we start off by drawing the dot structure for CO2. Carbon has four valence electrons. Oxygen has six. And we have two of them. So 6 times 2 gives us 12. 12 plus 4 gives us 16 valence electrons to deal with for our dot structure.
