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 H2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
Hydrogen - Element information, properties and uses | Periodic Table
Hydrogen is an essential element for life. It is present in water and in almost all the molecules in living things. However, hydrogen itself does not play a particularly active role. It remains bonded to carbon and oxygen atoms, while the chemistry of life takes place at the more active sites involving, for example, oxygen, nitrogen and phosphorus.
