Is metallic hydrogen stable at room temperature?
As a synthetic material, metallic hydrogen would also have endless applications. First off, it is believed to have superconducting properties at room temperature, and is meta-stable (meaning that it will retain its solidity once it returns to normal pressure).
Is metallic hydrogen reactive?
Atomic hydrogen is very reactive. It combines with most elements to form hydrides (e.g., sodium hydride, NaH), and it reduces metallic oxides, a reaction that produces the metal in its elemental state.
What are the properties of metallic hydrogen?
Because the electrons are unbound, they can move easily between the nuclei — a property associated with metals. This is metallic hydrogen: hydrogen that behaves like a metal. Metallic hydrogen is conductive, and it’s believed to be largely responsible for the dynamo that powers Jupiter’s and Saturn’s magnetic fields.
Why is metallic hydrogen a good rocket fuel?
Basically, because it takes so much energy to squish hydrogen into its metallic state, when they recombine into their molecular form (two hydrogen atoms bonded together), they release huge amounts of heat. And because hydrogen is the lightest element, it would be tens of times lighter than existing rocket propellants.
How strong is metallic hydrogen?
Since the first work by Wigner and Huntington, the more modern theoretical calculations point toward higher but nonetheless potentially achievable metalization pressures of around 400 GPa (3,900,000 atm; 58,000,000 psi).
Is hydrogen malleable or not malleable?
Hydrogen is a non metal because it does not form metallic bonding. It has a medium electronegativity not a low electronegativity like most metals. Hydrogen is not a conductor, is not malleable.
How can hydrogen become stable?
Hydrogen becomes chemically stable by sharing an electron with another hydrogen atom. Combining a hydrogen molecule consisting of two atoms with one oxygen atom forms the compound we know as water.
How cold is metallic hydrogen?
If you trap some in a bottle and pull the temp down to 33 kelvins (minus 400 degrees Fahrenheit, or minus 240 degrees Celsius), hydrogen becomes a liquid, and at 14 K (minus 434 degrees F or minus 259 degrees C), it becomes a solid.
Which fuel is most powerful?
Atomic metallic hydrogen, if metastable at ambient pressure and temperature could be used as the most powerful chemical rocket fuel, as the atoms recombine to form molecular hydrogen.

Is metastable metallic hydrogen the future of rocket propulsion?
Metastable metallic hydrogen may have potential as a highly efficient rocket propellant, with a theoretical specific impulse of up to 1700 seconds, although a metastable form suitable for mass-production and conventional high-volume storage may not exist.
Can solid hydrogen be used as a stable metallic element?
In that 2011 release, a scientist proposed doctoring solid hydrogen to help scientists induce a metallic phase change with less pressure. The quest for a stable metallic hydrogen will likely continue for decades, but the work of this French research team is potentially a huge landmark along the way.
Can metallic hydrogen be used as a rocket fuel?
Atomic metallic hydrogen, if metastable at ambient pressure and temperature could be used as the most powerful chemical rocket fuel, as the atoms recombine to form molecular hydrogen.
What is the metallic hydrogen phase?
Metallic hydrogen. Metallic hydrogen is a phase of hydrogen in which it behaves like an electrical conductor. This phase was predicted in 1935 on theoretical grounds by Eugene Wigner and Hillard Bell Huntington. At high pressure and temperatures, metallic hydrogen can exist as a liquid rather than a solid,…
