(a) Interpretation: The total number and arrangement of the electrons pairs for the indicated atom in the given ion is to be predicted. Concept Introduction: The representation of an element along with its valence electrons is referred to as Lewis symbol or Electron Dot Symbol. The electrons which are present in valence shell are represented by dots around the symbol of an element. The Lewis structure exhibits the connection between atoms. The geometry of molecule is determined by electron pair present around the central atom. The formula to calculate electron pairs in compound is, Electron pairs = bond pairs + lone pairs .

What possible error(s) exist in the Lewis structure (assume we are trying to represent the best
possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)?
[:ö==S:
N=
CO
:O:
The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with
three lone pairs on the sulfur.
There are no errors. This is the best possible structure.
The Lewis structure above does not minimize formal charges, thus is the not the best possible structure.
The nitrogen atom has an expanded octet, and this structure is impossible.
The Lewis structure contains the wrong number of electrons, thus this structure is impossible.
