What is the ion formula for ammonium?

The ion formula for ammonium is represented as NH4+. This means that the ammonium ion is composed of one nitrogen atom (N) and four hydrogen atoms (H), resulting in a positively charged ion. The "+" sign indicates that it carries a positive charge, which is due to the presence of one fewer electron compared to the neutral molecule.

In this case, the ammonium ion plays a significant role in various chemical reactions and is commonly found in fertilizers and biological systems, particularly within the context of nitrogen metabolism. Its formation is crucial for providing nitrogen in a usable form for plants. Understanding the properties and behavior of ammonium and other ions is essential in both chemistry and biological sciences, particularly for students pursuing studies in health sciences.
