(a)
Interpretation:
The element Na needs to be classified as molecular, network covalent, ionic or metallic.
Concept introduction:
In order to identify the structure of a material/compound, one often looks at what types of bonds hold the constituent particles together. For example, molecular solids refer to a substance where the constituent particle i.e. molecules are held together by van der Waal forces. Similarly, metals contain metallic ions surrounded by a sea of delocalized electrons that ultimately form the lattice structure. Each type of bonding provides a set of unique characteristics to the substance. Moreover, the nature of inter-particle bonding is more important in determining the nature of substance.
