How do you calculate lattice parameter of orthorhombic crystals?
Lattice parameter refers to the physical dimension of unit cells in a crystal lattice. The lattice parameter will need to be calculated differently depending on the lattice structure: Simple cubic, Body-centered cubic, or Face-centered cubic.
Lattice parameter of metal A and B are 2 and 4 what will be lattice parameter of alloy AB A20B and A50B?
Indeterminate. If the atoms form a perfectly mixed solution then you might guess 2a+4b where a and b are the fractions of A and B. But if they form a super-lattice where the stacking of the atoms only repeats over a long range (as happens in the many structures of silicon carbide [silicon and carbon are not metals]) then you can get almost anything, with various seemingly unconnected sequences and lattice lengths, even in different directions. For very dilute things like A50B you will get the normal lattice period of A over much of a crystal but with lattice distortions around the occasional B atom. That would cause a broadening of x-ray diffraction patterns.
What is the number of atoms per unit cell in cubic closed packing arrangement?
Face Centered Cubic (FCC) crystal structure has 4 atoms contained per unit cell. The relationship of of radius (R) to the lattice parameter (a) is 4R = a(sqrt(2)). In terms of lattice parameter (a)it is equal to, a = 2R(sqrt(2)).
What is difference between crystal lattice and space lattice?
crystal lattice is the orientation of atom in uniform manner with same characterized.where as space lattice is the three dimensional orientation of atom with different existing property.
What is the difference between a lattice and a polymer?
A lattice is made out of ions by charge attraction and a polymer is made of one or several monomers bonded covalently.
What is the value of the lattice parameter of iron?
0.286 nm
The lattice parameter of SiC is 4.36 and that of diamond is 3.57 is this difference large or small?
Large. Consider that the lattice parameter for C only changes about 0.2% from 300 to 1000 K.
What is the use of reciprocal lattice in crystal?
In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier Transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum space or less commonly k-space, due to the relationship between the Pontryagin momentum and position. The reciprocal lattice of a reciprocal lattice is the original or direct lattice.
What is the relationship between lattice energy and ionic bond strength?
The more lattice energy there is, the more the ionic bond attracts electrons from other atoms forming new compounds.

How can salt be identified?
- after taste - by chemical analysys - by microscopic examination of the crystals - measuring some physical parameters as refractive index, lattice parameter etc.

Electrostatic attraction between ions causes the release of what?
it releases lattice energy
