A solid compound is made of two elements, A and B. Atoms of A occupy all the corners of a cubic unit — Solid State Chemistry Question

💡 Solution & Explanation

Atoms of A at the 8 corners contribute $1/8$ each to the unit cell ($8 \times 1/8 = 1$). Atom B is at the body center, completely within the unit cell, contributing 1 ($1 \times 1 = 1$). The ratio of A:B is 1:1, making the formula $AB$.
