Question

How many total constituent particles are present in simple cubic unit cell ?

• A. $1$
• B. $3$
• C. $4$
• D. $2$

Answer 1

Answer: (A)

$1$

Answer 2

A simple cubic lattice has only eight atoms on the comers. As the contribution by each $=\frac{1}{8}$

Therefore, number of constituent particles (atoms) present in a unit cell $=\frac{1}{8} \times 8=1$
