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.
Stellar nucleosynthesis is the process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions in the cores and their overlying mantles. Stars are said to evolve (age) with changes in the abundances of the elements within.
