CLOSED PACKING IN 3D

Close Packing In 3d

Atom Arrangement In 1D, 2D And 3D|Voids|Hexagonal Close Packing|Cubic Close Packing|OMR

the coordination no. in 3D close packing of spheres having packing of the type (ABC) (ABC) is Y. calculate the value of Y/2

Close Packing In 1d And 2d

3D Close Packing || Formation OF Triangular void after Placing First (A) Layer || Formation OF Tv and Ov after Placing Second (B) Layer, ABAB.... || type OF Packing - HCP (Z,CN) || Packing Fraction OF Unit Cell || Volume OF Atoms and unit Cell

The difference in coordination numbers of hexagonal close packing in 3D and square close packing in 2-D, of identical spheres is:

Close Packing in Crystal (i) 1D - Close Packing,(ii) 2D - Close Packing,(a) Square Close Packing, (b) Hexagonal Close Packing,(iii) 3D - Close Packing Seven Types OF Crystal System (Trick to Remember)

Calculate the value of (Z)/(10). Where z = co-ordination number of 2D-square close packing + Co-ordination number of 2D-hcp + Co-ordination number of 3D-square close packing + Co-ordination number of 3D, ABCABC........packing + Co-ordiantional number of 3D, ABAB.......packing .

The co-ordination number in 3D-hexagonal close packing is

Assertion: Hexagonal close packing in more light than cubic close packing. Reason: Hexagonal close packing has C.N of 12 whereas cubic close packing has C.N. of 8.
