What is crystal structure? Explain its types.

• Crystal structure refers to the random arrangement of atoms in a material.
• Crystal structure is the ordered arrangement of atoms in a crystalline material, with types including Simple Cubic, Body-Centered Cubic, Face-Centered Cubic, Hexagonal Close-Packed, and Diamond Cubic.
• Types of crystal structure include Liquid, Gas, and Plasma.
• Crystal structure is only found in organic compounds.

Define coordination number and atomic packing factor

• Coordination number is the total number of atoms in a crystal; atomic packing factor is the density of the material.
• Coordination number is the number of nearest neighbors; atomic packing factor is the fraction of volume occupied by atoms.
• Coordination number refers to the total number of electrons; atomic packing factor is the weight of the atoms in a unit cell.
• Coordination number is the distance between atoms; atomic packing factor is the size of the atoms.
