Question

$\text{Match the following}\text{Unit Cell}\text{Lattice points in unit cell}\left(1\right)\text{FCC}\text{(i) 8}\left(2\right)\text{BCC}\text{(ii) 9}\left(2\right)\text{Primitive}\text{(ii) 14}$

• A. 1-(i), 2-(ii), 3-(iii)
• B. 1-(iii), 2-(ii), 3-(i)
• C. 1-(iii), 2-(i), 3-(ii)
• D. 1-(i), 2-(iii), 3-(ii)

Answer 1

The correct option is B

1-(iii), 2-(ii), 3-(i)

We know about FCC, BCC and Primitive unit cell.

8 lattice points (corners)

9 lattice points (8 at corners, 1 at body center)

14 lattice points (8 at corners, 6 at face centers)
