(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 .
