Whenever the crystalline solids are broken they do so along definite planes known as:

Correct answer: A. Cleavage planes

  • A. Cleavage planes
  • B. Refractory planes
  • C. Sagittal planes
  • D. Coronal planes

Explanation

In the context of crystalline solids, cleavage planes refer to specific planes along which a crystal can break or split easily. These planes are determined by the arrangement of atoms within the crystal lattice and reflect the internal structure of the crystal.

About Crystalline Solids

Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
