Close packing in crystals: In order to understand the packing of the constituent particles in a crystal, it is assumed that these particles are hard spheres of identical size. The packing of the crystals is done such that they occupy the maximum available space and hence the crystal has maximum density. For more details, click Part - 04

The cubic system is the simplest to analyze mathematically (although other systems can also be analyzed accordingly) and the analysis reflects the following characteristics.  for more information click on Characteristics

                       T he solid-state represents the physical state of matter in which the constituent molecules, atoms, or ions have no translatory motion although they vibrate about the fixed position that they occupy in a crystal lattice.                                               For characteristics, classification of solids read the following file: Day - 01 Solid-state
