Calculate the density of silver which crystallizes in a face centred cubic lattice with unit cell length 0.4086 nm (At. mass of Ag = 107.88)

Solution:
We have given that

Unit cell length,
a = 0.40806 nm  = 4.086 x 10-10 m

If fcc lattice the number of atoms per unit cell,
i.e. Z = 4

M for Ag = 107.88 g mol-1

Density of Ag, d =

Thus the density of silver is 1.051 x 104 kgm-3

Why are solids rigid?

Solids are rigid because the internuclear distance between the  molecules of a solid are very less and closely packed and their positions are fixed due to the strong forces of attraction between them.

Refractive index of a solid is observed to have the same value along all directions. Comment on the nature of this solid. Would it show clevage property?

Refractive index of a solid which have the same value along all directions are isotropic in nature. It would not show cleavage property.

Why is glass considred a super-cooled liquid?

Glass is amorphous solids and  have a tendency to flow, though very slowly. Therefore, these are called pseudo solids or super cooled liquids .
