What is the total contribution of all corner particles in bcc unit cell?
Options
- A1 particle
- B2 particles
- C3 particles
- D4 particles
Correct answer
A. 1 particle
Step-by-step solution
In a body-centered cubic (bcc) unit cell, particles are present at all 8 corners and 1 particle is present at the body center. Each corner particle is shared by 8 adjacent unit cells. Thus, the contribution of one corner particle to a single unit cell is 1 8 . Since there are 8 corners in a unit cell, the total contribution of all corner particles is 8 1 8 = 1 particle. Answer: 1 particle
