Collect the information about reactivity of VIIA group elements ( noble gases ) from internet or from your school liberary and prepare a report in their special character when compared to other elements of periodic table .

Explanation

1 ) The elements of Group VIIA ( noble gases ) are chemically inactive , because all of them have stable "Octet " configuration except He .
2 ) He has two electrons in the outermost orbital i.e., is orbital can accommodate maximum of two electrons i .e., ` 1s ^(2) ` Hence " He" is also inactive
3 ) The losing or gaining an electron or sharing of electron is differcult due to high I .E and zero E.A values of inert gases .
4 ) Under suitable consitions the heavier elements of the group form compounds with `F_(2) and O_(2) or XeF_(2) or XeO_(2) F_2`
5 ) Ar forms coordination conditions compounds the with `BF_(3) ` , whose composition is Ar .n. `BF_(3 ) `
6 ) Xenon Hexa fluoro platinate (IV )` (Xe [pt F_(6 )]) ` was prepared by N. Barltel . This was the first compounds of inert gases . After this compounds of Xenon with `F_(2) and O_(2) ` were prepared
7 ) The compounds of inert gases have found varied applications in recent times .
