Hydrogen gas
Hydrogen gas (Hâ‚‚) is the simplest and most abundant element in the universe, consisting of two hydrogen atoms bonded together. It is colorless, odorless, and highly flammable. Hydrogen can be generated through processes like electrolysis of water or natural gas reforming. It is used in various industries, including fuel cells for clean energy, in manufacturing, and as a rocket fuel due to its high energy content. When burned, hydrogen primarily produces water, making it a promising environmentally friendly energy source. Despite its versatility, handling hydrogen requires careful safety measures because of its flammability.
