Category: Hydrogen

Hydrogen is a chemical element with the symbol H and atomic number 1. It is the lightest and most abundant element in the universe, primarily found in stars and gas giants. Hydrogen is a colorless, odorless, and tasteless gas at room temperature and pressure, consisting of diatomic molecules (H2) in its most common form. It plays a crucial role in various chemical processes and is a key fuel source in energy production, especially in the form of hydrogen fuel cells. Hydrogen can exist in different isotopes, including protium (the most common, with no neutrons), deuterium (one neutron), and tritium (two neutrons, radioactive). In addition to its applications in energy, hydrogen is fundamental in the formation of water and organic compounds, making it essential for life on Earth.
