ammonia

Ammonia is a simple chemical compound made of one nitrogen atom bonded to three hydrogen atoms, represented as NH₃. It is a colorless gas with a strong, pungent smell. Ammonia occurs naturally in the environment, such as in decomposing organic matter, and is produced industrially for use in fertilizers, cleaning products, and refrigeration. It plays a vital role in the nitrogen cycle, supporting plant growth. Despite its usefulness, ammonia can be hazardous; concentrated forms are toxic and can cause burns or respiratory issues, so proper handling and safety measures are essential.
