High School Physical Science: Carbon Chemistry - Carbon Bonding

Concept Summary

• Carbon bonding is a chemical process where carbon atoms share electrons to form covalent bonds.
• Carbon can form a wide variety of bonds with other elements, including hydrogen, oxygen, nitrogen, and more.
• The unique ability of carbon to form long chains and rings is due to its ability to form strong covalent bonds with itself.
• Carbon bonding is essential for the formation of organic compounds, which make up the majority of living organisms.
• The type of bond formed between carbon atoms and other elements depends on the electronegativity of the atoms involved.
