in a unit cell, atoms A,B,C,D are present at half of total corners, all face-centres, body centre and one third of all edge-centres respectively. then formula of unit cell is??
1)AB3CD3 2)ABCD 3)AB6C2D2 4)AB6C2D4
Atoms at the corner in a unit cell is 1
No of atoms of A in one unit cell = ½
Atoms at the corner in a unit cell is 3
No of atoms of B in one unit cell = 3
Atoms at the body center in a unit cell is 1
No of atoms of C in one unit cell = 1
Atoms at the edge center in a unit cell is 3
No of atoms of D in one unit cell = 1
Formula is A1/2B3CD or AB6C2D2
No of atoms of A in one unit cell = ½
Atoms at the corner in a unit cell is 3
No of atoms of B in one unit cell = 3
Atoms at the body center in a unit cell is 1
No of atoms of C in one unit cell = 1
Atoms at the edge center in a unit cell is 3
No of atoms of D in one unit cell = 1
Formula is A1/2B3CD or AB6C2D2
