1.	which of the following statements are correct ?A. The coordination number of each type of ion in CsCl crystal is 8.B. A metal that crystallizes in bcc structure has coordination number of 12.C. A unit cell of an ionic crystl shares some of its ions with other unit cells.D. The length of the edge of unit cell of NaCl is 552 pm `( r_(Na^(+)) = 95 " pm " , r_(Cl^(-)) = 181 "pm")`
Answer» (d) is correct because length of unit cell =` 2(r_(Na^(+)) + r_(Cl^(-)))= 2 ( 95 + 181)` pm a and b are also correct. Only (b) is wrong because for a metal with bcc structure. Coordination number = 8.
