Q28 / 180 · KCET 2008 · Chemistry

A compound is formed by elements and. This crystallises in the cubic structure where the atoms are at the corners of the cube and atoms are at the body centres. The simplest formula of the compound is

  • Correct answer
    A
    $\mathrm{A} \mathrm{~B}$
  • B
    $\mathrm{A}_{6} \mathrm{~B}$
  • C
    $\mathrm{A}_{8} \mathrm{~B}_{4}$
  • D
    $\mathrm{AB}_{6}$

Solution

Since atoms are present at the corners of the cube, Number of atoms per unit cell $=8 \times \frac{1}{8}=1$ Number of $\quad$ atoms per unit cell $=1$ ( $\because$ present at the body centre of the cube) Hence, the formula of the compound $=A B$

Hence, the correct answer is option: 'A'.
