Hydrogen is a diatomic molecule (H2) [58]. It has an atomic weight and number of 1.00797 and 1, respectively, and is the first element in the periodic table with an electronic configuration of 1s1. H2 is one of the lightest elements on Earth, with a density of 0.08967 kg/m3, ...
Hydrogen, being the first element in the periodic table, has the simplest electronic structure of any atom, and the hydrogen molecule contains the simplest covalent chemical bond. Nevertheless, the phase diagram of hydrogen is poorly understood. Determining the stable structures of solid hydrogen is ...
