Write Lewis symbole for the following atoms and ions : S andS^(2 - ):

1.	Write Lewis symbole for the following atoms and ions : S andS^(2 - ): Al and Al^(3+) , and H^(-)
Answer» Solution :`._(16)S = 2, 8, 6 therefore ` Lewis symbol =` : overset (cdotcdot )(S):, S^(2-) ions = [ :UNDERSET(cdotcdot) overset( cdotcdot )S:]^(2-)` ` _(13)Al= 2,8,3 therefore` Lewis symbol`CDOT overset(cdot)Alcdot ,Al^(3+) ions [Al]^(3+)` ` _(1)H = 1therefore ` Lewis symbol= ` H^(cdot ), H^(-) ion = overset(H) (cdot)` .
