1.	Silver crystallises with face-centred cubic unit cells. Each side of the unit cell has a length of 409 pm. What is the radius of an atom of sliver ? ( Assume that each face atom is touching the four corner atoms).
Answer» SOLUTION :For face-centred cubic unit cell of an ELEMENT , ` r = a/(2SQRT2) = 0.3535a= 0.3535 xx 409 "PM" = 144.6 "pm" `
