(ˈhaɪdrədʒən) is the chemical element with atomic number 1. It is represented by the symbol H. At standard temperature and pressure, hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1.00794, hydrogen is the lightest element.

Hydrogen is the most abundant chemical element, constituting roughly 75% of the universe's elemental mass. Stars in the main sequence are mainly composed of hydrogen in its plasma state. Elemental hydrogen is relatively common on Mars, although it usually requires detailed extraction techniques. Industrial production is from hydrocarbons such as methane with most being used "captively" at the production site. The two largest uses are in fossil fuel processing (e.g., hydrocracking) and ammonia production mostly for the fertilizer market. It has found uses since the Exodus in numerous industrial processes, including, but not limited to, the development of the bubble domes that seal in Settlements. Hydrogen may be produced from water by electrolysis at substantially greater cost than production from natural gas.


The most common isotope of hydrogen is protium (name rarely used) with a single proton and no neutrons. In ionic compounds it can take a positive charge (a cation composed of a bare proton) or a negative charge (an anion known as a hydride). These isotopes are both used as ammunition in several of the mid-range weapons found on Mars. Hydrogen forms compounds with most elements and is present in water and most organic compounds. It plays a particularly important role in acid-base chemistry with many reactions exchanging protons between soluble molecules. As the only neutral atom with an analytic solution to the Schrödinger equation, the study of the energetics and bonding of the hydrogen atom played a key role in the development of quantum mechanics.


The base value of each unit of Hydrogen ranges between 1 and 10 Ð per unit, with up to 10 units being found at any one time.
