What are two properties of hydrogen?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
What are the properties and uses of hydrogen?
Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.
What is the important property of hydrogen?
The earliest known important chemical property of hydrogen is that it burns with oxygen to form water, H2O; indeed, the name hydrogen is derived from Greek words meaning “maker of water.”
What are the properties of hydrogen bond?
Properties of Hydrogen Bonding
- Solubility: Lower alcohols are soluble in water because of the hydrogen bonding which can take place between water and alcohol molecule.
- Volatility: As the compounds involving hydrogen bonding between different molecules have a higher boiling point, so they are less volatile.
What are 5 facts about hydrogen?

- Hydrogen is the most abundant element on earth. Hydrogen is an alternative fuel that has very high energy content by weight.
- Fuel cells can be used to power several applications.
- Fuel cells are a clean way to produce power.
- Fuel cell cars are very similar to traditional gasoline powered cars.
What happens if we breathe hydrogen?
Inhaled hydrogen gas (H2) has been shown to have significant protective effects on ischemic organs. Clinical trials abroad have shown promise that treatment of patients suffering from stroke, cardiac arrest, or heart attacks may benefit from inhaling hydrogen gas during the early recovery period.
Is hydrogen fuel renewable?
Currently, most hydrogen is produced from fossil fuels, specifically natural gas. Electricity—from the grid or from renewable sources such as wind, solar, geothermal, or biomass—is also currently used to produce hydrogen.
What properties make hydrogen unique?
Hydrogen is unique in that it can act like a metal in an ionic compound, donating electrons to the non-metal it bonds with or like a non-metal in a molecular compound, sharing electrons with another atom . Hydrogen has a relatively high electronegativity, which contributes to its affinity for bonding and to its diatomic nature.
What are the characteristics of hydrogen?
Characteristics of hydrogen. The hydrogen atom is the lightest known (atomic mass of 1.00794) and has a single electron in its outer layer, so its valence is 1. It is a non-metallic atom, highly oxidizable , with a single proton in the nucleus.
What are the physical and chemical properties of hydrogen?
Physical Properties of Hydrogen. Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1. It has an average atomic weight of 1.0079 amu, making it the lightest element.
What are the properties of dihydrogen?
Physical Properties of Dihydrogen At room temperature, this diatomic molecule of hydrogen is found in a gaseous state It is an absolutely colorless, odorless and tasteless gas which makes it very hard to detect It is the lightest element of our periodic table. It also has the lowest density of all elements It is highly combustible or inflammable.
