Liquid metallic hydrogen is a phase of hydrogen that occurs under extremely high pressures, typically above 400 GPa (gigapascals). In this state, hydrogen exhibits metallic properties, such as electrical conductivity, due to the dissociation of hydrogen molecules into individual atoms that can move freely. This phase is of significant interest in astrophysics, particularly in understanding the interiors of gas giant planets like Jupiter, where such conditions are thought to exist. Additionally, it has potential applications in advanced propulsion systems and superconductors.
What else can I help you with?
Which jovian planets contain metallic hydrogen?
It is believed that both Jupiter and Saturn contain metallic hydrogen in their interiors due to the extreme pressure and temperature conditions. Uranus and Neptune are not thought to have metallic hydrogen in their interiors.
What is the internal layering of Jupiter from the center outward?
Jupiter has a core made of rock and metal at its center, surrounded by a layer of metallic hydrogen. Above this is a layer of liquid metallic hydrogen, followed by a layer of molecular hydrogen. The outermost layer consists of clouds of ammonia and water vapor.
Why is hydrogen placed with nonmetals?
Hydrogen hasn't metallic properties.
Is MgH2 a metallic hydride?
Yes, MgH2 is a metallic hydride because it is a compound formed between a metal (Mg) and hydrogen (H). Metallic hydrides have characteristics such as high hydrogen storage capacity and can release hydrogen gas under certain conditions.
What are the layers of Jupiter made out of?
The crust is made out of gaseous hydrogen. then the layer underneath is liquid hydrogen, after is metallic hydrogen. the core is made out of rock. the light stripes on the surface are called zones and the dark ones are belts
Does earth have liquid metallic hydrogen?
No. Liquid metallic hydrogen only forms when hydrogen is subjected to extreme pressure. Hydrogen is present in trace amounts in Earth's atmosphere in gas form, under low pressure. The core is composed primarily of iron. Liquid metallic hydrogen likely exists in the gas giants Jupiter and Saturn.
What produces liquid metallic hydrogen?
Liquid metallic hydrogen is theorized to be produced under extremely high pressure conditions, such as found in the cores of gas giant planets like Jupiter and Saturn. The pressure causes hydrogen gas to undergo a phase transition into a metallic state, where the electrons are delocalized and the material exhibits properties of a metal.
Which planet has flowing liquid metallic hydrogen as the source of its magnetic field?
Saturn

Which planet likely has flowing liquid metallic hydrogen as the source of its magnetic field?
Jupiter is the planet that likely has flowing liquid metallic hydrogen in its interior, creating a magnetic field that is the strongest in the solar system. This metallic hydrogen is thought to exist under tremendous pressure in Jupiter's core, generated by the planet's immense mass.
A special fact about planet Jupiter?
It's core has a surrounding layer of liquid metallic hydrogen
Can you make the hydrogen a metal?
Yes. Although hydrogen is a non-metal, there is metallic hydrogen. It is formed when hydrogen is sufficiently compressed and undergoes a phase change; it is an example of degenerate matter. Solid metallic hydrogen consists of a crystal lattice of protons with a spacing which is significantly smaller than a Bohr radius. Indeed, the spacing is more comparable with an electron wavelength. The electrons are unbound and behave like the conduction electrons in a metal. As is the dihydrogen molecule H2, metallic hydrogen is an allotrope. In liquid metallic hydrogen, protons do not have lattice ordering.
Is metallic hydrogen the same as hydrogen?
Metallic hydrogen is a physical state that hydrogen enters under extreme pressure.
Why is Jupiter made of liquid metallic hydrogen?
Jupiter is a very massive planet composed mostly of hydrogen. It is massive enough that below a certain depth the pressure from the overlying layers is enough to convert the hydrogen into its liquid metallic state.
Which planets have a metallic hydrogen core?
It is hypothesized that gas giants like Jupiter and Saturn have metallic hydrogen cores deeper within their atmospheres. These cores are formed under extremely high pressure, where hydrogen behaves like a metal. However, direct evidence of these cores is still a subject of ongoing scientific research.
What is a metallic solid?
Mercury is the only metal which is liquid at room temperature. Hydrogen is sometimes considered to be a metal and is a gas at room temperature.
