A compound is formed by elements A and B . This crystallises in the cubic structure, where the A atoms are at the corners of the cube and B atoms are at the body centres.
Options
- AA B
- BA₆ B
- CA₈ B₄
- DA B₆
Correct answer
A. A B
Step-by-step solution
A occupies corner of unit cell. Number of A atoms =8 1 8 =1B is at body centre. Number of B atoms =1 1=1 The simplest formula of compound aligned &A: B &1: 1=A B aligned
