how are crystalline solids classified on the basis of nature of bonding? explain with examples.
Answers
Answer:
On the basis of nature of bonding, crystalline solids are classified as:
Molecular solids – The constituent particles are molecules.These solids may be polar such as HCl where molecules are held by dipole- dipole interactions, non-polar such as Cl2 where molecules are held by weak London forces or hydrogen bonded such as ice.
Ionic solids - The constituent particles are ions. The cations and anions are bound by strong electrostatic forces.Example NaCl.
Metallic solids – Metals which consists of positive ions surrounded by and held together by a sea of free electrons.example Fe, Cu etc.
Covalent solids – Non metals where the atoms are held together by covalent bonding throughout the crystal.Example graphite.
