Dihydrogen forms composed of two hydrogen atoms linked by a covalent bond, connected by a strong covalent bond. Its molecular weight is about 2.016 u, making it the lightest molecule. At room temperature it is a colorless, odorless, highly flammable gas. Sparingly soluble in water due to its nonpolar nature. Its H–H bond is exceptionally strong, yielding a high bond dissociation enthalpy around 435 kJ/mol, which governs its chemical reactivity and inertness under ambient conditions.

www.vyyuha.comDihydrogen is the homonuclear diatomic molecule formed from two hydrogen atoms. This molecule features a covalent bond between two hydrogen atoms, satisfying each of their required duet configurations. Since hydrogen is the lightest element on the modern periodic table, dihydrogen is the lightest known molecule. Since the standard atomic weight of the hydrogen atom is 1.008u, the molecular weight of the dihydrogen molecule is 2.016 atomic mass units.
