This module covers ionic and covalent chemical bonding. This material is covered in Chapter 7 of Flowers et al. (2017). Since we've already discussed ionic bonding as it results from reduction-oxidation in Module 4, this lecture focuses on covalent bonding. Hope you remember some of the covalent bonding patterns if you are taking spring term Organic Chemistry!
