Hydrogen is just as plentiful as uranium is scarce.

Hydrogen bonding is the chemical interaction that underlies the base-pairing rules described above.

Hydrogen cyanide is produced by the combustion or pyrolysis of certain materials under oxygen-deficient conditions.

Hydrogen ( ) is a chemical element with symbol H and atomic number 1.

Hydrogen is a concern in metallurgy as it can embrittle many metals, complicating the design of pipelines and storage tanks.

Hydrogen is not found without its electron in ordinary chemistry ( room temperatures and pressures ), as ionized hydrogen is highly chemically reactive.

The ' Hydrogen on Demand ' process ( see direct borohydride fuel cell ) creates hydrogen as needed, but has other issues, such as the high price of the sodium borohydride that is the raw material.

The latest stable version is Mandriva Linux 2011 (" Hydrogen ").

Hydrogen is an extreme example of this form of condensation.

* The Hydrogen Moderated Self-regulating Nuclear Power Module ( HPM ) is a reactor design emanating from the Los Alamos National Laboratory that uses uranium hydride as fuel.

Hydrogen is also being developed as an electrical power storage medium.

Hydrogen is not a primary energy source, but a portable energy storage method, because it must first be manufactured by other energy sources in order to be used.

Once the Hydrogen at the core is consumed it expands into a red giant ( 4 ), then sheds its envelope into a planetary nebula and degenerates into a white dwarf ( 5 ).

** Hydrogen dissolves rather well in metals, especially in palladium ; this is studied as a means of hydrogen storage.

* Hydrogen is an excellent coolant.

* Hydrogen is environmentally-friendly

Hydrogen is combined with CO < sub > 2 </ sub > ( absorbed from air or water ) to form glucose and release oxygen.

* November 25 – Heavy Hydrogen, later named Deuterium, is discovered by chemist Harold Clayton Urey.

Hydrogen peroxide is a harmful byproduct of many normal metabolic processes ; to prevent damage to cells and tissues, it must be quickly converted into other, less dangerous substances.

Hydrogen peroxide is used as a potent antimicrobial agent when cells are infected with a pathogen.

Hydrogen peroxide is naturally produced by the body and catalase breaks it down.

Hydrogen gas is ducted through this core, heated, and expelled from a rocket nozzle.

Hydrogen and helium are by far the most abundant elements in the universe.

Hydrogen and helium are most common, from the Big Bang.

* Hydrogen has nearly 30 % higher specific impulse ( about 450 seconds vs. 350 seconds ) than most dense fuels.

Hydrogen and helium are most common, residuals of the Big Bang.

After this, people realised most stars consist of Hydrogen.

Hydrogen is the most abundant element, and it is the basic building block for all other elements as its nucleus has only one proton.

Hydrogen spillover is the most common example of an adsorptive spillover.

Hydrogen peroxide has the advantage that it decomposes to form oxygen and water thus leaving no long term residues, but hydrogen peroxide as with most other strong oxidants is hazardous, and solutions are a primary irritant.

* Fission-Fusion-Fission, referring to the component stages of the most common type of Hydrogen Bomb with a Fission primary, a Fusion core, and an outer blanket of natural Uranium.

General Motors is also a regular sponsor of the event, and has in recent years sponsored the Hydrogen Fuel Cell Car competition held at NSB, where 16 teams compete to build the fastest or most powerful fuel cell-powered miniature car.

Hydrogen is the most common non-carbon atom that is bonded to carbon and, for simplicity, is not explicitly drawn.

Hydrogen was found in most sections of the hole, correlated with helium.

Hydrogen and helium are the most commonly used lift gases.

Hydrogen has been called one of the least efficient and most expensive possible replacements for gasoline ( petrol ) in terms of reducing greenhouse gases ; other technologies may be less expensive and more quickly implemented.

Hydrogen embrittlement is the process by which various metals, most importantly high-strength steel, become brittle and fracture following exposure to hydrogen.

Hydrogen and carbon monoxide are the most common background gases in a well-designed, well-baked UHV system.

The National Renewable Energy Laboratory sponsors NMSB, and General Motors is also a regular sponsor of the event and has in recent years sponsored the Hydrogen Fuel Cell Car competition held at NMSB, where teams compete to build the fastest or most powerful fuel cell-powered miniature car.

Hydrogen is one of the most technological important impurities in semiconductors, including diamond.

* Hydrogen breath test-it is becoming more and more common for people to undertake a medical test for clinical diagnosis of dietary disabilities such as fructose intolerance, fructose malabsorption, lactose intolerance and lactulose intolerance.

Hydrogen is the only element that has different names for its isotopes in common use today.
