Concept explainers
(a)
Interpretation:
Hypothetical element X forms a solid, it could crystalizes in three ways. The unit cell being either simple cubic, face centered cubic or body centered cubic.
(a) Which crystalline form of solid X has maximum density is to be identified.
(b) Which crystalline form of solid X has the more empty space has to be identified.
Concept introduction:
- Unit cell: A simplest repeating unit in the crystal structure. Every unit cell is described in terms of lattice point. Example for unit cell: cubic, monoclinic, tetragonal, orthorhombic, rhombohedral, hexagonal and triclinic.
- Simple cubic unit cell: The unit cell in which lattice points are located only at corners.
- Body centred cubic unit cell: The simplest repeating unit in the centre of the cubic structure.
- Face centred cubic unit cell: The identical particles present in the eight corners of the u it cell. But this structure contains same particle in the six centres of the faces.
