With the help of electron spins, clearly distinguish between Ferromagnetic, Antiferromagnetic and Ferrimagnetic substances.

How will you distinguish between ferromagnets, antiferromagnets and ferrimagnets with the help of electron spins ?

Distinguish between Conduction electrons and ions

Give reasons : (i) In stoichiometric dfects. NaCl exhibits Schottky defect and not Frenkel defect. (iii) Ferrimagnetic substances show better magnetism than antiferromagnetic substances.

Distinguish clearly between temporary and permanent hardness.
