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.
Jupiter is the planet known to have a liquid metallic hydrogen core. This unique state of hydrogen occurs under the immense pressure and temperature conditions found within Jupiter, allowing hydrogen to behave like a metal and conduct electricity. The presence of this liquid metallic hydrogen core contributes to Jupiter's strong magnetic field and is a key factor in its overall structure.
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.
Saturn
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.
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.
The metallic region is between the inner and outer core of the Earth; contain iron and nickel.
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.
It's core has a surrounding layer of liquid metallic hydrogen
There are two layers of liquid hydrogen. The innermost layer is "liquid metallic hydrogen". Also, the liquid hydrogen is not the "core". We are not certain, but it is thought the core is a rocky core.Nobody knows what metallic hydrogen looks like, and there would be no light to see by, but since we're already ignoring every possible detail by presuming that we're not being instantly killed, why should we let a tiny thing like that stop us? My guess is that the boundary between metallic hydrogen and non-metallic hydrogen is not going to be at all like the air/ocean boundary on Earth, but more like the boundary between a liquid and a gas right at the critical point... a sort of fuzzy transition that's not at all distinct. It would probably "feel" more like being underwater (very light, very hot water) mixed with a kind of fogginess.
Deep inside Jupiter hydrogen is in a very dense condition due to extreme pressure. This dense condition is called "metallic hydrogen" because then it can conduct electricity. On Earth the pressure is simply not strong enough to produce metallic hydrogen.
like Jupiter, Saturn has a large, rocky core at its center, about 10 times the size of earth.
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.
