Los elementos: el hidrógeno

Hydrogen, the lightest and most abundant element, has a single proton in its atomic structure. It is highly reactive and flammable, playing a crucial role in energy production, such as in the Sun and hydrogen bombs. On Earth, hydrogen is used in various applications, including rocket fuel and inflating balloons. Hydrogen fuel cells are a promising technology for generating clean energy, offering a non-polluting alternative to gasoline. Hydrogen constitutes about three-quarters of the universe's mass, making it a key element in both terrestrial and cosmic contexts.
