Hydrogen is the simplest and most abundant chemical element in the universe, represented by the symbol "H" and atomic number 1. It consists of one proton and one electron, forming a colorless, odorless, and highly flammable gas under standard conditions. As the primary component of stars like the Sun, hydrogen fuels nuclear fusion, releasing immense energy. On Earth, it plays a vital role in water (H₂O) and organic compounds. Lightweight and versatile, hydrogen is a promising clean energy carrier, with potential applications in fuel cells and green energy solutions. However, it rarely exists naturally in its pure form and typically requires extraction from compounds like hydrocarbons or water.
