The human body provides a great context for learners to apply their understanding of covalent bonding

Covalent bonds are far more common in the human body than other types of bonds. That is because approximately 96% of the mass in our body is made from four non-metallic elements: carbon, hydrogen, oxygen and nitrogen.
