hydrogenoidien
Hydrogenoidien is a hypothetical state of matter, also known as hydridic matter, where hydrogen atoms exist in a metallic, electron-rich state under extreme pressure. Unlike the more commonly discussed metallic hydrogen, which involves protons and a sea of electrons, hydrogenoidien suggests a scenario where hydrogen gains electrons to form hydride-like ions, H-, in a metallic lattice. This state is theorized to occur at pressures even higher than those predicted for metallic hydrogen, possibly within the interiors of gas giant planets like Jupiter and Saturn. The presence of these hydride ions would significantly alter the electronic and magnetic properties compared to pure metallic hydrogen. Research into hydrogenoidien is largely theoretical, relying on computational modeling and theoretical physics to explore its potential properties and the conditions under which it might exist. Experimental verification remains a significant challenge due to the immense pressures required. Understanding such exotic states of matter is crucial for refining planetary interior models and advancing our comprehension of fundamental physics under extreme conditions.
