Carbon’s small size allows its nucleus to hold onto shared pairs of electrons strongly, resulting in the formation of strong covalent bonds. In contrast, elements with larger atoms tend to form weaker bonds.

Compounds containing carbon are exceptionally stable due to the strong bonds that carbon forms with most other elements. These strong bonds contribute to the longevity and structural integrity of carbon-based molecules.

The properties of carbon compounds depend on the elements other than carbon present in the molecule. Different elements can impart specific characteristics such as reactivity, solubility, and conductivity to the compounds.

Carbon commonly forms compounds with oxygen, hydrogen, nitrogen, sulfur, chlorine, and various other elements, resulting in diverse compounds with specific properties.

Carbon’s valency of four allows it to form stable covalent bonds with up to four other atoms, either carbon or atoms of other monovalent elements.
