Concept:

• Viscosity: It is a property of a fluid to oppose relative motion between its layer.
  • The coefficient of viscosity is “η“ and dimension is [ ML^-1T^-1].
• Kinetic Viscosity: It is a measure to the inherent resistance of the of a fluid to flow when no external force is acted expect gravity.
  • Kinetic Viscosity = coefficient of viscosity / fluid mass density
  • V = η / ρ

Explanation:

• Dimensional formula of viscosity is [ ML^-1T^-1].

Explanation:

• The metallic property of the elements of the periodic table decreases when we move across the group whereas it increases when we go down the group, as we go down the number of electrons increases and thereby their distance from the nucleus increases. 
• This increase causes them to shed more electrons and thereby have a greater electropositive or metallic character. 

Among the given compounds Na shows maximum Metallic character.
