Which failure occurs when a sodium chloride crystal is mechanically stressed?

💡 Explanation

Applied stress causes charged ions to align with similarly charged ions and electrostatic repulsion cleaves the crystal via electrostatic repulsion effects, rather than breaking covalent bonds directly because the ionic bond is non-directional; therefore crack propagation occurs.
