If ' \( a \) ' is the length of unit cell, then which one is correct relationship?
(1) For simple cubic lattice,
Radius of metal atom \( =\frac{a}{2} \)
(2) For bcc lattice,
Radius of metal atom \( =\frac{\sqrt{3} a}{4} \)
(3) For fcc lattice,
Radius of metal atom \( =\frac{a}{2 \sqrt{2}} \)
(4) All of these
