Lewis structure of Sb 2 F 7 − has to be predicted. Concept Introduction: Lewis structures represent covalent bonds and describe valence electrons configuration of atoms. The covalent bonds are depicted by lines and unshared electron pairs by pairs of dots. The sequence to write Lewis structure of some molecule is given as follows: The central atom is identified and various other atoms are arranged around it. This central atom so chosen is often the least electronegative. Total valence electrons is estimated. single bond is first placed between each atom pair. The electrons left can be allocated as unshared electron pairs or as multiple bonds around the symbol of element to satisfy the octet (or duplet) for each atom. Add charge on overall structure in case of polytatomic cation or anion.
