A body centre cubic lattice is made up of two different types of atoms A and B . Atom A occupies the body centre and B occupying the corner positions. One of the corners is left unoccupied per unit cell. Empirical formula of such a solid is

Options

  1. AA B
  2. BA₂ B₃
  3. CA₅ B₇
  4. DA₈ B₇

Correct answer

D. A₈ B₇

Step-by-step solution

There is one A per unit cell aligned & Number of B per unit cell = 1 8 7= 7 8 & aligned Empirical formula & =A₁ B_ 7 / 8 & =A₈ B₇ aligned aligned
