Information on hydrogen gas
Hydrogen gas is?
Hydrogen gas is ?This gas is the lightest chemical element found on Earth’s surface. This gas is the most abundant gas in the universe, as it occupies seventy-five percent of the size of the universe.
The discoverer of this gas was Henry Cavendish, and that was one thousand seven hundred and sixty-six AD.
Physical properties of hydrogen gas:
Normally, this gas has no color.
This gas belongs to the group of nonmetals, and has an electron configuration of 1s1.
The ionization energy of this gas is about 1312 kilojoules per mole, while the electronic affinity for it is 72.8 kilojoules per mole. With regard to electronegativity, it is 2.2.
When talking about the properties of the hydrogen atom, it is mentioned that the radius of the atom is 53 * 10 ^ -12 meters.
It is reported that the boiling temperature of this gas is about 20.28 K, while the melting temperature is 14.01 Kelvin.
The speed of sound through a hydrogen atom is about 1270 meters per second.
Hydrogen is present in most cases in molecular form, as it forms a covalent bond with other atoms, especially when forming water and organic compounds .
Chemical properties of hydrogen gas:
Chemically, a single hydrogen atom consists of one proton and one electron, and hence it has been relied upon in explaining the theory of the atomic structure.
Hydrogen is produced industrially by performing the electrolysis process of water.
Scientists have found that there are three main isotopes of hydrogen: protium, deuterium and tritium.
Uses of hydrogen:
Hydrogen gas has many uses and applications, and this comes as follows:
It is used as fuel for various means of transportation, including airplanes and cars.
This gas is used as a battery for portable personal computers.
This gas is used to generate thermal energy.
It is used as the main fuel in nuclear reactors.
This gas is used as a protective gas in welding processes.
It is used to detect the presence of micro-leaks in the systems used in power plants and in the chemical industries.
