Number of atoms per unit cell in B.C.C. is:
The intermetallic compound $$LiAg$$ crystallizes in a cubic lattice in which both $$Li$$ and $$Ag$$ atoms have coordination numbers of $$8$$. To what crystal class does the unit cell belong?
The unit cell belongs to a body-centered like structure.
In $$LiAg$$ intermetallic compound, the bigger atom will form the simple cubic unit cell and the smaller atom will be at the centre of the body. This type of structure is called body centred cubic like structure.
Number of atoms per unit cell in B.C.C. is:
If a is the edge length, In BCC, the distance between two nearest atoms will be:
CsBr crystallizes in a body-centered cubic lattice. The unit cell length is 436.6 pm. Given that the atomic mass of Cs = 133 and that of Br = 80 amu and Avogadro number being $$6.02\times 10^{23}$$ mol$$^{-1}$$, the density of CsBr is:
The radius of the largest sphere which fits properly at the centre of the edge of body centred cubic unit cell is:(Edge length is represented by '$$a$$')
An element has a body centered cubic (bcc) structure with a cell edge of $$288 pm$$. The atomic radius is
Body centred cubic lattice has a co-ordination number of:
An example of a body cube is:
Packing fraction in BCC lattice is
The low density of alkali metals is due to
What is the theoretical density of crystalline $$K$$?
