Question

Stability of a crystal is reflected in the magnitude of its melting point. Comment.

Answer 1

1. The stability of a crystal is reflected in the magnitude of its melting point because it indicates the amount of energy required to overcome the forces holding the particles (ions, atoms, or molecules) together in the crystal lattice.
2. A higher melting point means that stronger intermolecular or interionic forces are present, which in turn suggests that the crystal is more stable.
3. Conversely, a lower melting point indicates weaker bonding forces and lower stability.

Hence, the greater the melting point of a crystal, the more stable its structure.
