How many atoms per unit cell in bcc
WebHere's why: The unit cell structure gives us a way to relate a and r. This is based on particular vectors in the unit cell which span exactly (N) touching atoms (again assuming the atoms are hard spheres). For example, the edge of an SC unit cell spans 2 atoms, thus a=2r. For FCC, 4 atomic radii are spanned across the unit cell face diagonal ... WebCorrect option is A) In bcc unit cell, 1 atom is present at the center of the body and 8 atoms are present at the 8 corners of body. The atom at the center of body contributes fully to the unit cell. The contribution of each corner atom to the unit cell is one eight. Hence, the total number of atoms in the unit cell is 81×8+1=2.
