1.	Which of the following statement(s) is (are) correct ?
Answer» The co-ordination number of each TYPE of ion in CsCl crystal is 8 A metal that crystallises in BCC structure has a co-ordination number of 12 A unit CELL of anioniccrystal shares some of itsion with other unit cells The length of unit cell in NaCl is 552 pm. `(r_(Na^+)=95 "pm", r_(Cl^-)= 181 "pm")` Solution : Co-ordination number of each ion in CsCl is 8. A unit cell of an IONIC crystalshares some of its IONS with other unit cells.
