The charge of nitrite is -1. This indicates that nitrite is a negatively charged ion.
Understanding Nitrite: A Key Anion
Nitrite (NO₂) is a crucial polyatomic ion found in various chemical and biological systems. As specified in the reference, nitrite is a negatively charged ion composed of one nitrogen atom and two oxygen atoms. Its defining characteristic, from a charge perspective, is its formal charge of -1.
Key Characteristics of Nitrite
- Ionic Nature: Nitrite exists as an ion, meaning it carries an electrical charge due to an imbalance of protons and electrons. In the case of nitrite, it has an excess of one electron, leading to its negative charge.
- Composition: It consists of one nitrogen atom covalently bonded to two oxygen atoms.
- Charge Significance: The -1 charge is fundamental to its chemical reactivity and how it interacts with other ions and molecules in solutions. For instance, it will be attracted to positively charged ions (cations) to form ionic compounds.
