(a)
Interpretation:
Whether or not the given sole fact supports the possible identification of the sample as
Concept introduction:
A unit cell of the crystal is the three-dimensional arrangement of the atoms present in the crystal. The unit cell is the smallest and simplest unit of the crystal which on repetition forms an entire crystal. Unit cell can be a cubic unit cell or hexagonal unit cell. The classification of a unit cell depends on the lattice site occupied by the atoms.
(b)
Interpretation:
Whether or not the given sole fact supports the possible identification of the sample as
