The cyanide ion, represented as CN⁻, is a negatively charged ion consisting of a carbon atom triple-bonded to a nitrogen atom. It is known for its high toxicity and is often associated with various chemical processes, including industrial applications and certain biological mechanisms. In nature, CN⁻ can be found in some plants and seeds, where it serves as a defense mechanism against herbivores. Due to its lethal properties, exposure to cyanide can be dangerous, leading to severe health effects or even death if ingested or inhaled in significant amounts.
