Under standard conditions, hydrogen is a gas of diatomic molecules with the formula H2, called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is …

6 days ago · The Kawasaki H2 hit dealers at the end of last year, and side-by-side enthusiasts immediately went out and added the big, green, supercharged bus to their fleet. But now, just a few …

Apr 18, 2025 · Hydrogen (H 2), a diatomic molecule consisting of two hydrogen atoms covalently bonded, holds a position of paramount importance in chemistry, physics, and increasingly, in …

Aug 29, 2025 · When two hydrogen atoms approach, their single electrons are shared. This sharing creates a single covalent bond, often represented as H-H, forming the H2 molecule. The shared pair …

Molecular hydrogen (H2) is a potent free radical scavenger that not only ameliorates oxidative stress but also lowers cytokine levels. The aim of the present study was to investigate the protective effects of …

NIST subscription sites provide data under the NIST Standard Reference Data Program, but require an annual fee to access. The purpose of the fee is to recover costs associated with the development of …

Feb 2, 2022 · Hydrogen is the lightest and simplest element with the symbol H. It consists of only one electron and one proton and, under normal conditions, it exists primarily in its diatomic form as …

Liquid hydrogen (H₂ (l)) represents the cryogenic liquid state of molecular hydrogen, existing below its critical temperature of 33.0 K. This cryogenic fluid exhibits a boiling point of 20.28 K at standard …

H2 is the chemical formula for the diatomic molecule of hydrogen, which is the simplest and most abundant element in the universe. This term is crucial in understanding the phases and classification …

This page discusses hydrogen (H), the first element, primarily as the diatomic molecule (H2), a colorless, odorless gas used in industries like ammonia and methanol production.
