Concept explainers
(a)
Interpretation:
Whether the statement that one atom present at one corner of unit cell, then there must be same type of atom at all corner of unit cell is true or false has to be determined.
Concept Introduction:
Unit cell represents lattice structure if it stacked together repeatedly with no gaps and rotations. This can also produce whole crystals by stacking method. Basic type of unit cells is as follows:
1. Simple cubic (SC).
2. Body centered cubic (BCC).
3. Face centered cubic (FCC).
(b)
Interpretation:
Whether the statement that unit cell must be defined to show atoms at corners is true or false has to be determined.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Whether the statement that if one face has atom at its center then opposite face also has atom at its center is true or false has to be determined.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
Whether the statement that if one face has atom at its center then all faces also have atom at their center is true or false has to be determined.
Concept Introduction:
Refer to part (a).
