Hydrogen is the simplest and most abundant element in the universe, consisting of just one proton and one electron. It is a colorless, odorless, and highly flammable gas at room temperature.
Represented by the symbol H and atomic number 1, hydrogen is found naturally in stars, water, and many organic compounds. Though rarely found on its own on Earth, it can be produced from natural gas, water electrolysis, or biomass, making it a versatile resource.
