Q43.A metal crystallizes in a face centred cubic structure. If the edge length of its unit cell is 'a', the closest approach between two atoms in the metallic crystal will be (1) 2√2a (2) √2a a (3) (4) 2a √2
What This Question Tests
This question tests the understanding of the geometry of face-centred cubic (FCC) structures and the calculation of the closest approach distance between two atoms based on the edge length.
