The chemical element represented by the symbol H is Hydrogen. It is the simplest and lightest element on the periodic table, consisting of only one proton and one electron. Hydrogen is abundant in the universe, primarily found in stars, including our Sun, and is essential for the formation of more complex elements through nuclear fusion. On Earth, hydrogen is a crucial component of water and organic molecules, playing a vital role in various biological and chemical processes. Hydrogen is also gaining attention as a potential clean energy source, particularly in fuel cells and hydrogen-powered vehicles.
