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.

description
Element 1 is a hard dark-red solid. A 10. g cube of it is set on a hot plate.
After 10 minutes, the temperature of the top of the cube has risen by less
than 1 °C.
Element 2 is a moderately soft silvery-gray solid. A 5 cm x 5 cm square
of it, only 1 mm thick, is flexed slightly by hand. The sheet snaps in half.
Element 3 is a moderately soft silvery-gray solid. A small cube of it is put
into a ceramic crucible and heated strongly. It melts about not far above
