Chemical Bonding: Lewis symbol & structure for [S & S*2-]

Lewis symbol & structure for S & S*2-

      S - Sulphur

Atomic no.- 16

1s2, 2s2 2p6, 3s2 3p4

Total No of electron (e-) in outer most orbit :-- 4

Thus, Valency :- 6    (2+4 )   (3rd orbit)

  

                  Structure

     

There, is Six (6) electron in its orbit or it is a electronegative element.

    Now, 

    S*2-

Sulphur 2*-  means that sulphur gained two electrons.

     s*2-  ( Sulphur 2*-  )

Atomic no.- 16

1s2, 2s2 2p6, 3s2 3p6 [+2 Gained Electron ].  

( Full filled orbital due to gained electron pair)
