Hydrogen atom

A hydrogen atom is the simplest and most abundant type of atom in the universe. It consists of one proton at its center, forming the nucleus, and one electron that orbits around it. Hydrogen is essential for the formation of stars and fuels nuclear reactions in those stars, including our Sun. It plays a key role in water and organic compounds, making it vital for life. Because of its simple structure, hydrogen is a fundamental building block in chemistry, leading to the creation of other elements through fusion and chemical reactions.
