An element 'X' has bcc lattice as shown below:
The unit cell length a is 306pm

What is the distance between nearest neighbours?

A compound AB crystallines in bcc lattice with unit cell edge length of 380 pm. Calculate the distance between oppositely charged ions in the lattice.

Xenone crystallizes in the face centred cubic lattice and the edge of the unit cell is 620 pm. What is the nearest neighbour distance and radius of xenon atom?

Iron crystallizes in several forms. At 1185 K, the body centred cubic alpha form of iron changes to the face centred cubic gamma form of iron. Assuming that the distance between the nearest neighbours is the same in two forms at the transition temperature, calculate the ratio of the density of alpha form to that of gamma form at the transistion temperature.

A new unit of length is chosen such that the speed of light in vacuum is unity. What is the distance between the Sun and the Earth in terms of the new unit if light takes 8 min and 20 s to cover this distance ?

Two identical magnetic with a length 10 cm and weight 50 g of each are arranged freely with their like poles facing in a inverted vertical glass tube. The upper magnet hangs in the air above the lower one so that the distance between the nearest pole of the magnet is 3mm. Pole strength of the poles of each magnet will be

Silver crystallises with face centred cubic unit cells. Each side of the unit cell has a length of 409 pm. What is the radius of an atom of silver ? (Assu!'le that each face atom is touching the four corner atoms)

The vacant space in bcc lattice unit cell is

CsBr has bcc like structures with edge length 4.3Å . The shortest inter ionic distance in between Cs^(+) and Br^(-) is:
