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.

Jan 26, 2025 · 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

4 days ago · Hydrogen is the most abundant element in the universe; it is also the simplest and the lightest. Although hydrogen constitutes nearly 75% of all the universe’s matter, only a small fraction of the hydrogen accessible on Earth exists in a pure state (not bonded to other elements).

Hydrogen is the raw fuel that most stars 'burn' to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth. The sun's supply of hydrogen is expected to last another 5 billion years. From the Greek word hydro (water), and genes (forming).

2 days ago · There are many reasons why hydrogen won't be economically viable even in heavy-duty trucks. getty. In the first half of 2024, the global market for hydrogen fuel cell cars was just 5,621 units.

Hydrogen is a chemical element. It is the simplest element and the first in the periodic table. It has the symbol H and atomic number 1. Hydrogen also has a standard atomic weight of 1.008. This makes it the lightest element. Hydrogen is a gas at 15 degrees Celsius (59 degrees Fahrenheit) at standard atmosphere (and in many other

Feb 23, 2023 · Hydrogen is a clean alternative to methane and is the most abundant chemical element, estimated to contribute 75% of the mass of the universe. Find out why hydrogen is important as a future clean energy source to fuel our homes and businesses.

Hydrogen is one of the three most abundant elements present on Earth. It was discovered in 1766 by Henry Cavendish and is widely used for various industrial, medical and recreational purposes.

Hydrogen is a colorless, odorless gas. It is easily ignited. Once ignited it burns with a pale blue, almost invisible flame. The vapors are lighter than air. It is flammable over a wide range of vapor/air concentrations. Hydrogen is not toxic but is a simple asphyxiate by the displacement of oxygen in the air.

Jan 31, 2025 · Geologic hydrogen, also known as natural hydrogen, is hydrogen gas that is naturally found below the surface of the Earth. Unlike hydrogen produced through industrial processes, geologic hydrogen is sourced by and stored in rocks in the ground, similar to traditional petroleum resources.Learn More:USGS Geologic HydrogenGeologic Hydrogen Prospectivity Map Explorer
