Tardigrade Admin · Accepted Answer

Atomic hydrogen is produced at high temperature in an electric are or under ultraviolet radiations The dissociation of dihydrogen at

2000 K

is only

0.081%

H-H bond dissociation enthalpy is highest for a single bond for any diatomic molecule.
Dihydrogen can be produced on reacting

with dil.

H Cl

as well as

N a O H

(aq.)
