A and B atoms in a crystal are positioned at the corners and face centers respectively. What is the formula of the crystal?

Options

  1. AA₂ B₃
  2. BA B₂
  3. CA B₃
  4. DA₂ B₃

Correct answer

C. A B₃

Step-by-step solution

Atoms of A are placed at the corners in a crystal. Thus, its contribution = 1 8 8=1 . Atoms of B are placed at the face centres in the given crystal. Thus, their contribution =6 1 2 =3 . Therefore, the formula of the crystal is A B₃ .
