A cubic lattice has \(A\) atoms at the body centre, \(B\) atoms at the corners, \(C\) atoms at half of the face centres. The formula of the lattice is
- A \(A B C_2\)
- B \(A B_2 C_4\)
- C \(A_2 B_2 C_3\)
- D \(A B C_3\)
Answer & Solution
Correct Answer
(C) \(A_2 B_2 C_3\)
Step-by-step Solution
Detailed explanation
\(A\) atoms are present at body centre. \(\therefore\) Number of atoms \(=1\) Contribution of body centre \(=1\) \(\therefore\) Effective number of atoms \(A=1 \times 1=1\) \(B\) atoms are present at cornres. \(\therefore\) Number of atoms at cornres \(=8\) Contribution of…
