Hydrogen, as a scientific topic, encompasses the study of the lightest chemical element (atomic number 1) across its atomic, molecular, ionic, and condensed phases, as well as its roles in physical chemistry, materials science, and energy research. It includes investigation of quantum properties of the hydrogen atom, isotopes (protium, deuterium, tritium), hydrogen bonding, and behavior under extreme conditions leading to phenomena such as metallic hydrogen. The topic also covers hydrogen’s function in acid–base chemistry, redox processes, plasma physics, astrochemistry, and its use as an energy carrier in technologies like fuel cells and hydrogen storage materials.
Natural hydrogen is considered a potential low-carbon energy source. But how much is generated underground—and how quickly? An international research team led by the LIAG Institute for Applied Geophysics in Hannover has published ...

The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...
Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar Maisenbacher and colleagues ...
Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...
