(A)-(III), (B)-(II), (C)-(III), (D)-(I) (A)-(I), (B)-(III), (C)-(II), (D)-(IV) (A)-(II), (B)-(III), (C)-(IV), (D)-(I) (A)-(IV), (B)-(III), (C)-(II), (D)-(I) |
(A)-(IV), (B)-(III), (C)-(II), (D)-(I) |
The correct answer is option 4. (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
Trigonal void (2-D void): These voids are formed due to surrounding of three spheres in same plane whose centres are at corners of a triangle. Coordination number of a particle present in trigonal void = 3
Tetrahedral void (T-voids): These voids are formed due to close packing of one corner atom and three adjacent face-centered atoms in a cubic unit cell. Surrounding spheres are located at the corners of a regular tetrahedron. Coordination number = 4
Octahedral voids (O-voids): These voids are formed due to overlapping of two trigonal voids of adjacent layers. Surrounding spheres are located at the corners of an octahedron. Coordination number = 6
Cubical voids: These voids are formed by close packing of eight corner atoms in a simple cubic unit cell. Coordination number = 8
