A compound AB crystallises in bcc lattice with the unit cell edge length of 380 pm . Calculate (i) The distance between oppositely charged Ions in the lattic. (ii)Radius of B^(−) if the radius of A^(+) is 190 pm.

Suppose the mass of a single Ag atoms is 'm' Ag metal crystallises in fcc lattice with unit cell edge length 'a' The density of Ag metal in terms of 'a' and 'm' is:

A metal crystallises in b.c.c. lattice. The per cent fraction of edge length not covered by atom is :
