Hydrogen - Wikipedia
Hydrogen is a chemical element; it has the symbol H and atomic number 1. It is the lightest and most abundant chemical element in the universe, constituting about 75% of all normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the formula H2, called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless ...
Hydrogen | Properties, Uses, & Facts | Britannica
Hydrogen, a colorless, odorless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The earliest known chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning ‘maker of water.’
Hydrogen - Department of Energy
Hydrogen is a highly versatile energy carrier and an input to several important chemical and industrial processes. When it is produced cleanly—from renewables, nuclear power, or fossil energy with carbon capture—it can play a vital role in reducing emissions from some of the hardest-to-decarbonize parts of our economy. These parts of our economy are also among our most energy-intensive and ...

Hydrogen Fuel Basics - Department of Energy
Hydrogen is a fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
Hydrogen atom - Wikipedia
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral hydrogen atom contains a single positively charged proton in the nucleus, and a single negatively charged electron bound to the nucleus by the Coulomb force.
Hydrogen - Element information, properties and uses | Periodic Table
Hydrogen has been around since atoms first formed in the residue of the Big Bang, and is the most abundant element by far. Despite billions of years of countless stars fusing hydrogen into helium it still makes up 75 per cent of the detectable content of the universe.
Hydrogen explained - U.S. Energy Information Administration (EIA)
Hydrogen is the simplest element Each atom of hydrogen has only one proton. Hydrogen is also the most abundant element in the universe. The sun, and other stars, are essentially giant balls of hydrogen and helium gases. On earth, hydrogen occurs naturally combined with other elements in liquids, gases, or solids. Hydrogen combined with oxygen is water (H 2 O). Hydrogen combined with carbon ...
