Which of the following unit cell types possess an effective number of particles () greater than or e — Solid State Chemistry Question

💡 Solution & Explanation

Simple cubic has $Z=1$. Body-centered cubic has $Z=2$. Face-centered cubic has $Z=4$. An end-centered unit cell has particles at 8 corners ($8 \times 1/8 = 1$) and 2 opposite faces ($2 \times 1/2 = 1$), yielding $Z=2$.
