# Ordinary hydrogen gas consists of di-atomic molecules in which two H-atoms unite together by covalent bond. This is known as molecular hydrogen. Stability of molecular hydrogen H-H bond energy is very high i.e, 104 Kcal per mole .Due to high bond energy ,molecule of hydrogen is very stable .It does not react under ordinary conditions .Only those reactions are possible in which at least 104 Kcal per mole of energy is available. (ii) Atomic hydrogen Hydrogen obtained by the dissociation of molecular hydrogen is called atomic hydrogen. Atomic hydrogen is very energetic and very reactive .It has a very …
