Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
Jan 26, 2017 · Metallic hydrogen has been created in the lab for the first time, by squeezing a sample of the element to pressures beyond what exists at the centre of the Earth. The creation of a substance...
Feb 3, 2020 · Well, the potential uses for hydrogen in general are widened if there’s a metallic form that scientists can access, and in the race for metallic hydrogen, the race itself is something of a grail ...
Apr 23, 2020 · In 1971, the Nobel Prize winning academician Vitaly Ginzburg compiled a list of the most important and interesting questions in physics and astrophysics facing us on “the verge of XXI century.” 1 The first and second problems in the list were controlled nuclear fusion and room temperature superconductivity, and the third was metallic hydrogen. How the simplest element in the Universe could ...
Jan 26, 2017 · Metallic hydrogen would be a fundamental breakthrough that could revolutionize energy use, space exploration and more. Image of a diamond anvil cell compressing molecular hydrogen. At 4.95 million atmospheres, the sample converts to metallic hydrogen, as shown on the right. Courtesy of R. Dias and I.F. Silvera.
Jan 29, 2020 · A milestone in the hunt for metallic hydrogen. An optical study of cold solid hydrogen at extreme pressures indicates that electrons in the material are free to move like those in a metal. This...
Jan 16, 2018 · The result, below roughly 8,000 miles (13,000 km) under the cloud tops, is a chaotic mix of free hydrogen nuclei — which are just single protons — intermingled with liberated electrons. The ...
