GENERAL KNOWLEDGE

Detailed explanation-1: -A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

Detailed explanation-2: -Solids that have a regular and three-dimensional arrangement of constituent particles such as (atoms, molecules, or ions) are known as crystalline solids. A few examples of crystalline solids include sodium chloride, quartz, diamond, etc.

Detailed explanation-3: -Related subjects: Materials science. In chemistry and mineralogy, a crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions. Generally, crystals form when they undergo a process of solidification.

Detailed explanation-4: -Crystalline solids are called true solids.
