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.
Although it is the smallest and lightest atom, hydrogen can have a big impact by infiltrating other materials and affecting their properties, such as superconductivity and metal-insulator-transitions. Now, researchers from ...
