A unit cell consists of a cube in which there are A atoms at the corners and B atoms at the face centres and A atoms are missing from two corners in each unit cell. What is the simplest formula of the compound ? |

Answer» Solution :No. of A atoms PER unit cell = `6 XX 1/8= 6/8` No. of B atoms per unit cell = `6 xx 1/2 = 3` Thus, A:B :: `6/8` : 3 or `A_(6//8).B_3`. Hence, the simplest FORMULA is `A_6.B_(24)` or `AB_4` |
