1.	Out of NaCl and CsCl , which one is more stable and why ?
Answer» Solution :CsCl is more stable than NaCl. This isbecause higher the COORDINATION number, GREATER are the forces of ATTRACTION between the CATIONS and anions in the close-packed arrangement. As CsCl has co-ordination number of 8:8 while NaCl has a coordination number of 6 :6 , therefore, CsCl is more stable.
