Close Packing In 1d And 2d

Close Packing In 3d

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)

How will you distinguish between Hexagonal close packing and cubic close packing. (3D)

Distinguish between hexagonal close packing and cubic packing.

Mathc the type of packing given in Column I with the itmes given in Column II. Column -I (i) square close packing in two dimensions (ii) Hexagonal close packing in two dimensions (iii) Hexagonal close packing in three dimensions (iv) Cubic close packing in three dimensions Column -II (a) Triagnular voids (b) Pattern of spheres is reapted in every fourth layer (c) Coordination number -4 (d) Pattern of sphere is reapeated i alternate layers.
