Definition
Hydrogen is the lightest and most abundant chemical element in the universe, with the symbol H and atomic number 1. It is a colorless, odorless, and highly flammable gas at room temperature, commonly found in water (H₂O) and organic compounds. In energy contexts, hydrogen is used as a clean fuel source, producing only water vapor when burned. This element is essential for life and plays a key role in stars, including the Sun, where it undergoes nuclear fusion.
