How will you distinguish between tetrahedral void and octahedral void?
There are two main sorts of voids named as tetrahedral void and octahedral void.

Complete step by step answer:
| Tetrahedral voids | Octahedral voids |
|---|---|
| It can be found in substances having a tetrahedral arrangement in their crystal system. | It can be found in substances having an octahedral arrangement in their crystal system |
How will you distinguish between the following pairs of terms I tetrahedral and octahedral voids II crystal lattice and unit cell?
Tetrahedral void is surrounded by four spheres while an octahedral void is surrounded by six spheres.
How will you distinguish between HCP and CCP?
HCP and CCP structures both consist of layers of closest packed planes of atoms. Atoms in both structures have coordination numbers of 12. However the HCP structure contains only two types of planes, with an alternating .. ... A CCP structure contains three types of planes, with an alternating ..
What is tetrahedral and octahedral void?
A simple triangular void 'c' which is surrounded by four spheres is called as tetrahedral void. The double triangular void like 'd' which is surrounded by six spheres is called as octahedral void.
Where are tetrahedral voids located?
Two tetrahedral voids are present on each body diagonal of a fcc unit cell at a distance of 43 a from each corner.
Which void is bigger octahedral or tetrahedral?
No. The octahedral voids are bigger in size than tetrahedral one.
How do you distinguish between crystal lattice and unit cell?
Unlike crystal lattice, a unit cell has a definite volume and a specific number of points. Therefore a crystal lattice and unit cell coexist in a three-dimensional representation of atoms, ions or molecules in a crystal.
How many lattice points are there in face Centred tetragonal?
(b) In face centred tetragonal, the number of lattice points is also the same i.e., 8 + 6 = 14.
How many lattice points are there in one unit?
Answer: One unit cell of body centered has 8 lattice points are corners and 1 lattice points at faces, total 9 lattice points.
Is CCP same as FCC?
Face Centered Cubic (fcc) or Cubic Close Packed (ccp) These are two different names for the same lattice. We can think of this cell as being made by inserting another atom into each face of the simple cubic lattice - hence the "face centered cubic" name.
What is CCP unit cell?
The unit cell consists of four layers of atoms in a cubic close-packed (ccp) arrangement of atoms. The layers at the top and bottom contain six atoms at the hexagon corners and one atom at the middle of each hexagon. The packing quality is the proportion of the atoms directly occupied by the crystal (or unit cell).
What do you mean by packing efficiency?
The packing efficiency is the fraction of the crystal (or unit cell) actually occupied by the atoms. It must always be less than 100% because it is impossible to pack spheres (atoms are usually spherical) without having some empty space between them.
