Question
Sodium metal crystallizes in a body centred cubic lattice with a unit cell edge of 4.29(Ao). The radius of sodium atom is approximately :-
Options
A.5.72(Ao)
B.0.93(Ao)
C.1.86(Ao)
D.3.022(Ao)
Solution
For BCC, √3 × a = 4R
∴ R =
= 1.86 (Ao)
∴ R =
= 1.86 (Ao)Create a free account to view solution
