A metal crystallizes with a face-centered cubic lattice. The edge length of the unit cell is 408 pm. The diameter of the metal atom is :

Most crystals show good cleavage because their atoms, ions or molecules are

Glass is a

Iodine is a

The number of atoms contained in a fcc unit cell of a monatomic substance is

The ability of a substances to assume two or more crystalline structures is called

For a crystal system a = b = c and α = β = γ ≠ 90^o

A solid compound XY has NaCl structure. If the radius of the cation is 100 pm, the radius of the anion (Y^–) will be :

A body centric cubic lattice is made up of two different types of atoms A and B. Atom A occupies the body centre and B occupying the corner positions. One of the corners is left unoccupied per unit cell. Empirical formula of such a solid is

A compound with cubic structure is made of elements A and B. A atoms are at the corners of the cube and B atoms are at the face centres. The simplest formula of compound is
