In a fcc arrangement, the corner atoms ...

In a fcc arrangement, the corner atoms are A type and those at face centres are B type. What is the simplest formula of the compound ?

Text Solution

Verified by Experts

Number of A type atoms in the unit cell, `8 xx 1/8 =1`
Number of B type atoms in the unit cell, `6 xx 1/2 =3`
Hence the formula is `AB_3`
