Nascent Hydrogen. The hydrogen gas, which is just liberated as a result of a chemical is called nascent hydrogen or newly born hydrogen. It is obtained by passing dihydrogen gas at atmospheric pressure through an electric arc between two tungsten rods. The electric arc maintains a temperature around 4000 - 4500Â°C.
Hydrogen is the lightest and most abundant element in the universe. The hydrogen-helium abundance ratio is an important clue to the cosmological process. The nucleus of ordinary hydrogen consists of a single proton, but it also occurs as deuterium with a proton and a neutron.ydrogen burns in oxygen or air with an almost colorless flame and has potential as a fuel. Since it requires energy to separate hycrogen, its real potential is as a storage medium for energy; processes like electrolysis of water can produce hydrogen for storage as a fuel.
