In this unit we learned about covalent bonds. Covalent bonding is another type of bonding, so we took a used material from the last unit like the lewis structures. Along with this, we also learned about the types of shapes molecules form and why and how they form this way. We also learned how to draw organic structures, which are like lewis structures, but with a few changes. While I had done covalent bonding before, I had never done organic structures. I found that part somewhat challenging because I constantly forgot to add the hydrogen molecules in my structure. One question I still have is how the electron sharing between the covalent structure actually works. Specifically, where does it go, and why?
