Ammonium is formed when ammonia (NH₃) accepts a proton (H⁺), resulting in a positively charged polyatomic ion. Its tetrahedral structure consists of a nitrogen atom at the center bonded to four hydrogen atoms. Ammonium is significant in agriculture, as it serves as a nitrogen source in fertilizers, promoting plant growth. Additionally, ammonium compounds are utilized in cleaning products and various industrial processes due to their solubility in water.
