Detailed explanation-1: -A crystal is: a solid composed of atoms, ions, or molecules arranged in a pattern that is repetitive in three-dimensions. Each crystal structure within a specific crystal system is defined by a unit cell. A unit cell is the smallest repeatable subsection of the crystal.

Detailed explanation-2: -A crystal is a form of solid where the atoms are arranged in a predictable, specific arrangement. The atoms in a crystal form a repeating pattern called a crystal lattice. Examples of crystals include diamond, table salt and polymers (including plastics).

Detailed explanation-3: -In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal. The smallest repeating structure of a solid is called a unit cell, which is periodically repeated in three dimensions on a lattice.

Detailed explanation-4: -In the crystalline arrangement, the particles pack efficiently together to minimize the total intermolecular energy. The regular repeating pattern that the atoms arrange in is called the crystalline lattice.

Detailed explanation-5: -Lattice systems are a grouping of crystal structures according to the axial system used to describe their lattice. Each lattice system consists of a set of three axes in a particular geometric arrangement. All crystals fall into one of seven lattice systems.
