Manganese-55 (isotope)

Manganese-55 is an isotope of the element manganese, meaning it has 25 protons (defining it as manganese) and 30 neutrons in its nucleus, making its atomic mass 55 atomic mass units. It’s stable, meaning it doesn’t decay over time. Manganese-55 naturally occurs and makes up the majority of manganese found on Earth. It plays a vital role in biological processes, such as enzyme function, and is important in industrial applications like steel production and battery components. Its stability and natural abundance make it significant in both ecological and technological contexts.
