Which of the following statements are not true ?

1.	Which of the following statements are not true ?
Answer» An element with BCC structure has TWO atoms PER unit cell. An ionic COMPOUND `A^+ B^-` with BCC structure has one AB formula unit per unit cell. The shape of the octahedral void is octahedral The edge length of the crystal `A^+ B^-` is equal to the distance between `A^+` and `B^-` ions. Solution :Octahedral void is so called because it is SURROUNDED by SIX atoms. Edge length of `A^+ B^-` crystal =2 x distance between `A^+` and `B^-`
