Define (a) space lattice, (b) crystal lattice, (c) unit cell and (d) coordination number.

What is ‘crystal lattice’?

The vacant space in bcc lattice unit cell is

When the ratio of the radius of cation and anion in the crystal lattice is 0.53, the co-ordination number in the lattice is

How do you distinguish between crystal lattice and unit cell ?

The intermediate compound LiAg crystallises in a cubic lattice in which both Li and Ag atoms have co-ordination number of 8. To what crystal class does the unit cell belong

The intermetallic compound LiAg crystallizes in cubic lattice in which both lithium and silver have co-ordination number of eight. The crystal class is

How will you distinguish between the following pairs of terms: (i) Hexagonal close-packing and cubic close-packing? (ii) Crystal lattice and unit cell? (iii) Tetrahedral void and octahedral void?

A space lattice of a crystal has alternate positive and negative ion in the lattice. Comment.

For the structure of solid given below if the lattice points represent A^(+) ions and the B^(-) ions occupy the tetrahedral voids then coordination number of A and B may be
