en.wikipedia.org/wiki/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, and researchers think it might be present in large quantities in the hot and gravitationally compressed ...

Metallic hydrogen, like that found deep within Jupiter, is a familiar element with incredibly bizarre properties.

Metallic hydrogen is a state of hydrogen wherein the ordinarily gaseous or liquid material is converted to a metallic solid under immense pressure at low temperature. As yet, no one is certain that they have actually made the material, but they fe...

Metallic hydrogen is a sort of super-compressed hydrogen found in the cores of gas giants and stars. As hydrogen tops the Periodic Table's alkali metal column, it has been known for a while it has the potential to be a metal, but only under extreme pressures.

Team leader Isaac F. Silvera, who has spent more than 45 years working on metallic hydrogen, said for now they can't speculate on the fate of the sample. "Basically, it's disappeared," he told ScienceAlert over the phone. "It's either someplace at room pressure, very small, or it just turned back into a gas.

Liquid metallic hydrogen, which the planets Jupiter and Saturn are made of, is not an earthly substance. Even so, we might be able to get an idea of what it is from another substance called Mercury. Mercury is what is found in a thermometer. As shown in this picture, the element Mercury, at room ...
