HYDROGEN: POSITION OF HYDROGEN IN THE PERIODIC TABLE: Hydrogen has electronic configuration.On one hand, its electronic configuration is similar to the outer electronic configuration of all calimetals, which belonging to the first group of the periodic table. On the other hand, like halogen configuration belonging to the seventeenth group of the periodic table. It is short by one electron to the corresponding noble gas configuration helium . Hydrogen lose one electron to form un positive ions, as well with halogens, which gain electron to form uni negative ion. Loss of the electron from hydrogen atom results in nucleus H^+ of ~1.5 X 〖10〗^(-3) pm size. This is extremely small as compared to normal atomic and ionic sizes of 50 to 200 pm. As a consequence, H^+ does not exist freely and is always associated with other atoms molecules. Thus, hydrogen unique in behaviour and the best placed separately in the periodic table.
