In a A_x B_y crystal structure, A^ +y ions occupy all the tetrahedral voids and B ^ - x ions make BCC unit cell: What is the formula of the compound?

Options

  1. AA ₄ ~B ₂
  2. BA ₂ ~B ₄
  3. CA ₂ ~B ₂
  4. DA ₄ ~B ₄

Correct answer

A. A ₄ ~B ₂

Step-by-step solution

Number of A ^ + y ions =2 number of atoms per unit cell. Number of B ^ - x ions =2( BCC ) per unit cell. Number of A ^ + y ions =2 2=4 Formula = A ₄ ~B ₂
