Physical Properties and Uses of Hydrogen | Inorganic Chemistry
Physical Properties and Uses of Hydrogen Properties of the Hydrogen Molecule Hydrogen is the only element in the periodic table with atomic number 1 and electron configuration 1S1 with unique physical and chemical properties. Due to the presence of three isotopes, the molecular formula depicted as H2 (di-hydrogen), D2 (di-deuterium), and T2 (di-tritium). The chemistry study of hydrogen has late gained, fresh uses of H2 as fuel and alternative energy source when we remember huge stock of liquid in the earth as surface water. On the earth’s surface, hydrogen gas is the third most abundant element after oxygen and silicon and 2nd most abundant gases after oxygen. Therefore, Hydrogen has the only element in the periodic table, where the valence electron is directly influenced by the nucleus with no shielding electron. Hence the physical and chemical properties of hydrogen gases influence by this electron. With its single electrons, it represents a wide range of chemical bonding.
1. Its nS1 electron configuration justifies its position in Group-1 with the alkali metals. 2. But if we consider the electron configuration, one electron short to the next noble gas helium. Thus it placed in group-17 with halogen. 3. With its half-filled valence shell, H2 also placed group-14 with carbon and forms covalent chemical bonding with a wide range of polarities.
