Ionic bonds are bonds between very electronegative atoms and atoms with very low ionization energy, such as sodium chloride, where sodium loses an electron (having a new positive charge) and chlorine loses an electron (having a net negative charge). For more information, please refer to their website. This is simply a compilation of the unit into written summaries which can be used as an additional guidance for notes. Note: All information in this unit can be found on Khan Academy’s AP Chemistry unit. We learn about ionic, covalent, and metallic bonds, how to represent them, and how there are different ways to learn more about molecules’ shapes, polarities, and chemical bonds. Post is closed for comments.In this unit, we learn about different interactions between atoms depending on their individual characteristics. Our support team will be more than happy to help you.

I know that this probably isn’t the response you were looking for, but I hope you understand where we’re coming from.

We qualify our AP courses as supplemental courses because, among several other things, we are not able to provide laboratory experiences, feedback on free-response, or essay-type work that several AP courses require. These courses are not intended to be used in a stand-alone fashion or to take the place of a full, in-person AP course. However, bear in mind that our courses are not a replacement for work done in a typical AP classroom. We believe these resources help prepare students that are enrolled in AP classrooms by giving them extra practice and opportunities to better understand the material. Our content experts create content and align it to CollegeBoard’s AP Course and Exam Description. Please note that the AP courses available at Khan Academy are not directly reviewed by the CollegeBoard and, in consequence, not directly approved by them. It's wonderful to know that your son's using our AP courses! I understand that you'd like to know if your son would be fully prepared to take the 2021 AP exams afterward.
