Solid State Tes...

Which of the following pairs have layer lattice structure in solid state chemistry-

$$NH_3$$ and $$BF_3$$form an adduct readily because they form

Schottky defect is observed in the crystal of:

Amorphous solids are those which have:

An element $$X$$ (atomic mass $$= 24 gm/mol$$) forms a face centered cubic lattice. If the edge length of the lattice is $$4$$ x $$10^{-8}$$ $$cm$$ and the observed density is $$2.40$$ x $$10^{3}$$ $$kgm^{3}$$ then the percentage occupancy of lattice points by element $$X$$ is : (Use $$N_{A}$$ $$=$$ $$6$$ x $$10^{23}$$) 

The compound with the largest lattice energy would be:

Oxygen atom forms FCC unit cell with 'A' atoims occupying all tetrahedral voids and 'B' atoms occupying all octahedral voids. If atoms are removed from two of the body diagonals then determine the formula of resultant compound formed.

In an atomic bcc lattic what fraction of edge is not covered by atoms?

$$PQ$$ is $$NaCI$$ type solid $$P$$ occupies corners of cubic unit cell. If all the atoms present along face centered axis are removed, the resultant stoichiometry and $$%$$ decrease in the total number of atoms per unit cell are
