CONFIGURATION, POSSIBLE OXIDATION AND ISOTOPES OF HYDROGEN AND UNIQUE POSITION OF HYDROGEN OF HYDROGEN IN PERIODIC TABLE.

Hydrogen is the first element in the periodic table with nucleus and electron. It is a gas; diatomic molecule in which two atoms of hydrogen are covalently bonded. The atomic number of hydrogen is one. The electronic configuration of hydrogen is 1s1. It has oxidation number of +1 and -1

ISOTOPES OF HYDROGEN

Hydrogen exhibits Isotope with Hydrogen or protium [11H], Deuterium or heavy hydrogen [21H or D] and tritium [31H or T] as the Isotopes. These Isotopes have relative atomic masses of 1, 2 and 3 respectively.

HYDROGEN ISOTOPES

Isotopes of Hydrogen

The Isotopes have similar chemical properties but different physical properties although tritium is radioactive.

UNIQUE POSITION OF HYDROGEN IN THE PERIODIC TABLE

It can lose this single electron to form positive ions[H+] just like the elements in groups [Li, Na, K, Rb, Cs and Fr] and based on the argument it can be considered to be placed in group 1 along with group 1 elements.
