MHT CET Chemistry Question (2026) — Solution

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
