A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor. It cannot be stored in a traditional wet wing, and hydrogen tanks have to ...
is the least stable, while 7. H. is the most. Hydrogen is the only element whose isotopes have different names that remain in common use today: the 2. H. (or hydrogen-2) isotope is deuterium [6] and the 3. H. (or hydrogen-3) isotope is tritium. [7] The symbols D and T are sometimes used for deuterium and tritium.

The EU initiated the probe without an industry complaint, the first such trade case of this kind. The bloc is set to confirm on Thursday provisional duties of up to 37.6% on Chinese brands such as ...
Spin isomers of molecular hydrogen. Molecular hydrogen occurs in two isomeric forms, one with its two proton nuclear spins aligned parallel (orthohydrogen), the other with its two proton spins aligned antiparallel (parahydrogen). [1] These two forms are often referred to as spin isomers [2] or as nuclear spin isomers. [3]

Hydrogen line. The hydrogen line, 21 centimeter line, or H I line [a] is a spectral line that is created by a change in the energy state of solitary, electrically neutral hydrogen atoms. It is produced by a spin -flip transition, which means the direction of the electron's spin is reversed relative to the spin of the proton.
