Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.

2025年1月26日 · hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The hydrogen atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; an electron, bearing one unit of negative electrical charge, is also

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.

2023年2月23日 · Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe.

What is Hydrogen Gas? Hydrogen is the non-metal with the chemical symbol H. The molecular formula of hydrogen is H 2. Hydrogen has been recognized as a convenient, clean-burning fuel. It can be stored as a compressed gas or as a liquid and is suitable for internal combustion engines in automobiles. Hydrogen itself is non-toxic and not carcinogenic.

Hydrogen is the lightest element. Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 o F (-253 o C).

2023年2月5日 · 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 molecular hydrogen (H 2 gas). It is what powers the sun by fusion to produce helium.

What is Hydrogen. Hydrogen (pronounced as Hi-dreh-jen) is a colorless gas represented by the chemical symbol H. It is the first element in the periodic table, belonging to the family of nonmetals [1]. Since hydrogen is a diatomic gas, it’s denoted by the molecular formula H 2.

Hydrogen, symbol H, molecular formula H2 is a colorless, odorless, tasteless, flammable gaseous chemical substance in the periodic table. In chemistry or chemical science, the hydrogen atom is the only member of the chemical element in which the valence electron is under the direct influence of the nucleus.

Hydrogen is a potential solution for reducing greenhouse gas emissions and mitigating climate change. It can replace fossil fuels as a clean and renewable energy source, which can reduce air pollution and improve human health.
