Webhow to beat an aquarius man at his own game. is exocytosis low to high concentration. Home; About; Work; Experience; Contact 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.

WebThe BCC unit cell consists of a net total of two atoms, the one in the center and eight eighths from the corners. In the FCC arrangement, again there are eight atoms at corners of the unit cell and one atom centered in each of the faces. The atom in the face is shared with the adjacent cell. Web1.
