A compound contains two types of atoms $A$ and $B$ ．Its crystal structure is a cubic lattice with＇$A$＇ atoms at the corner of the unit cells and＇$B$＇atoms at the body centres．The simplest formula of the compound will be

If three elements $A, B, C$ crystalise in a cubic solid lattice with $B$ atoms at the cubic centres, $C$ aton at the centre of edges and A atoms at the corners, then formula of the compound is

Metallic conductors and semiconductors are heated separately. What are the changes with respect to conductivity?

What is the edge length of the unit cell of a body centred cubic crystal of an element whose atomic radius is 75 pm?

The number of atoms in body centred and face centred cubic unit cell respectively are

An element crystallises in a body centered cubic lattice. The edge length of the unit cell is 200 pm and the density of the element is 5.0 g cm\(-\)3. Calculate the number of atoms in 100 g of this element.

In the face centered cubic lattice structure of gold the closest distance between gold atoms is ('a' being the edge length of the cubic unit cell)

A compound formed by elements X and Y crystallises in the cubic structure, where X atoms are at the corners of a cube and Y atoms are at the centre of the body. The formula of the compounds is

In a close-packed body-centred cubic lattice of potassium, the correct relation between the atomic radius (r) of potassium and the edge-length (a) of the cube is
