(a)
Interpretation:
The greater contribution of the structure has to be identified.
Concept introduction:
The outer most shell of the element is called as valence shell. The electrons present in the outer shell are called valence electron.
For example:
Nitrogen element has seven electrons and it has two shells, the second shell is the valence shell and it has five electrons in the valence shell. The five electrons are called as valence electrons.
The number of valence electron of carbon is four, number of valence electron of oxygen is six, number of valence electron of nitrogen is five and the number of valence electron of hydrogen is one.
Resonance: The delocalization of electrons which is characterized as several structural changes.

- The percent ionic character of a bond between elements A and B may be approximated by the expression %IN = 100[1 - e^(-1/4(XA - XB))], where XA and XB are the electronegavities for the respective elements. What is the the percent ionic character of the interatomic bonds for Fe2O3? What type of bonding would you expect in Fe2O3?
