Study Notes
Carbon and its Compounds
- Carbon is present in many common items, including food, clothes, medicines, and books.
- Most of the items that are not made of metal or glass/clay are made of carbon compounds.
- Carbon compounds are not good conductors of electricity and have relatively low melting and boiling points compared to ionic compounds.
- This suggests that carbon compounds do not form ions, but instead form covalent bonds.
- Carbon has four valence electrons, and it requires gaining or losing four electrons to attain a noble gas configuration.
- However, gaining or losing four electrons would be difficult for the carbon atom due to its small size and the large amount of energy required.
Covalent Bonding
- Carbon atoms share electrons with other atoms to form covalent bonds, resulting in stable molecules.
- Covalent bonds are formed by the sharing of electrons between two atoms.
- This sharing of electrons often leads to atoms achieving a complete octet of electrons, meaning they will have eight electrons in their outer shell.
- Covalent bonds provide a more stable configuration for carbon atoms compared to ionic bonding.
- Covalent compounds do not conduct electricity because they do not form ions.
- Carbon's ability to form covalent bonds with other elements allows it to form a wide variety of compounds with diverse properties.
