Hydrogen Gas Formula

Hydrogen Gas Formula

One of the most basic members of the family of chemical elements, hydrogen is a colourless, odourless, tasteless and flammable gaseous substance. The Hydrogen Gas Formula contains an atom with a nucleus that contains a proton with one unit of positive electrical charge, as well as an electron with one unit of negative electrical charge. However, under normal conditions, hydrogen gas is a loose aggregation of hydrogen molecules, each of which consists of a pair of atoms, a diatomic molecule, i.e. H₂.

Hydrogen Gas Chemical Formula

Hydrogen Gas Formula is primarily composed of hydrogen atoms that form diatomic molecules. As a result, by looking at the hydrogen atoms, it is possible to determine the molecular composition of hydrogen gas. In molecules, hydrogen atoms are typically found bonded together in pairs. The Hydrogen Gas Formula is therefore written as H₂.

Hydrogen Gas Structural Formula

The chemical formula for hydrogen is H₂. Furthermore, its molar mass is affected by the hydrogen isotope under consideration. The molar mass of hydrogen, which is formed by two nuclei with one proton each, is 200 g/mol, while two nuclei form the mass of deuterium with one proton and one neutron each, which is 400 g/mol. And tritium, formed by two nuclei with one proton and two neutrons each, has a 600 g/ml mass. Furthermore, this molecule comprises two hydrogen atoms connected by a single ionic bond. 


Although Hydrogen Gas Formula is a very abundant gas throughout the universe, it can be found on Earth in the traces of the atmosphere as well as in some planets and stars such as Jupiter and the Sun, among others. We can also make it with the assistance of microorganisms.


It is made possible by the electrolysis of water, which yields molecules of hydrogen and oxygen. The enzymes known as hydrogenases are responsible for the biosynthesis of H₂ when it is created with the help of microorganisms.

Physical Properties

The Hydrogen Gas Formula is colourless. The density of this gas is 0.089 g/ml. It has a melting point of about 260 °C and a boiling point of about 252 °C.

Chemical Properties

The mixtures of this chemical compound with air have the potential to explode as well, but only at temperatures of at least 500 °C. This makes the chemical extremely reactive. It is no longer reactive at normal room temperature. In addition, Hydrogen Gas Formula can combine with other elemental compounds, like halogens, to form hydrides.


Rocket fuel is one of the most common uses of hydrogen gas for energy. NASA began using liquid hydrogen as rocket fuel in the 1950s, and they were the first to use hydrogen fuel cells to power the electrical systems on their spacecraft. Hydrogen Gas Formula is essential in converting crude oil into gasoline, fuel oils, and other products. Weather observation balloons are filled with equal parts hydrogen and helium.

Hydrogen Gas Formula is also widely used in transportation. It is used in fuel-cell electric vehicles and is considered extremely efficient.

Hydrogen fuel cells generate electricity by combining hydrogen atoms with oxygen atoms. Hydrogen is also used in the hydrogenation process.
