Hydrogen - Wikipedia
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.

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. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1]

Hydrogen explained - U.S. Energy Information Administration (EIA)
Hydrogen is an energy carrier. Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance. Hydrogen can be produced—or separated—from a variety of sources, including water, fossil fuels, or biomass and used as a source of energy or fuel.
