A cubic lattice has atoms of A at the body centre, atoms of B at the corners of the cube and atoms C at all the face centres. What is its formula?
Options
- AA B C₃
- BA B C₂
- CA B₂ C
- DA₂ B C₃
Correct answer
A. A B C₃
Step-by-step solution
Number of atoms of A=1 ( 1 atom is present at centre of cell) Number of atoms of B= Number of corners Contribution of each atom =8 1 8 =1 Number of atoms of C= Number of faces Contribution of each atom =6 1 2 =3 Therefore, formula of compound =A B C₃ .
