Three element `A,B,C` crystallize into a cubic solid lattice.Atoms `A` occupy the corners `B` atoms the cube centres and atom `C` the edge .The formula of the compound is

A

ABC

B

`ABC_(2)`

C

`ABC_(3)`

D

`ABC_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Astom A per unit cell `=8xx1/8=1`
Atom B per unit cell `=1`
Atom C per unit cell `=12xx1/4=3`
`A:B:C=1:1:3`
So, the formula is `ABC_(3)`
