In the Body Centred Cubic lattice what are the numbers of the nearest and next nearest neighbors?
There are eight nearest neighbours, and six next-nearest.
What Simple cubic body-centered cubic and face-centered cubic unit cells all have the same shape. How are they different?
The body-centered cubic system has a lattice point at each of the eight corner points of the unit cell plus one lattice point in the centre. Thus it has a net total of 2 lattice points per unit cell ( 1⁄8 × 8 + 1).The face-centered cubic system has lattice points on the faces of the cube, that each gives exactly one half contribution, in addition to the corner lattice points, giving a total of 4 lattice points per unit cell ( 1⁄8 × 8 from the corners plus  1⁄2 × 6 from the faces).
The lattice structure in a metal is?
A metallic lattice consists of positive ions in a 'sea' of outershell negative electrons which are delocalised and mobile through the metal structure. The lattice is held together by strong forces of attraction between the mobile electrons and the positive ions.
Why is there no face centered hexagonal lattice?
Simple reason - It violates the cubic symmetry. To see it from another perspective - Base centered cubic lattice is equivalent to a simple tetragonal lattice. Draw two unit cells adjacent to each other. Then connect the base center points to the corener points which are shared by these two unit cells. Then connect the two base centered point in each unit cell. Now you have a simple tetragonal lattice. Simple tetragonal lattice has one lattice point per unit cell compared to two lattice point per unit cell of base centered lattice. Always the lower lattice point lattice is considered for a given symmetry. Because of symmetry breaking, the symmetry of base centered cubic lattice is same as tetragonal lattice.
What are the macroscopic and microscopic properties of stainless steel?
Microscopically (what we can see through an electronic microscope), steel is seen in a shape of grains, particules, beans, but the submicroscopic strcture of steel is its crystalline structure: the ferrite is Cubic centred, austenite is cubic faced centred and martensite is like a parallelogram.
What is a face-centered cubic lattice?
face centred cubic lattice is one in which there a atoms at the each edge and at the centre of each face
In the Body Centred Cubic lattice what are the numbers of the nearest and next nearest neighbors?
There are eight nearest neighbours, and six next-nearest.
Why gold is more ductile than sodium?
Both gold and sodium are metals. Gold has face centred cubic crystal structure, sodium has body centered cubic structure. A face centred cubic structure allows an easy movement of dislocations in the lattice. Gold is extraordinarily ductile.
Is a salt crystal cubic in shape?
Yes. This is due to the face-centred cubic lattice structure of the crystals which have a cubical unit cell.
What type of structure does sodium possess?
Sodium in its elemental form is a metal. The crystal structure of the metal lattice is body centred cubic where each atom has eight near neighbours. This structure is adopted by all of the group 1 metals.

What does the structure look like with NaCl?
It is a face-centered cubic lattice.
What is the name of a repeating structure for salt?
It is a face-centered cubic lattice.
Why are salt crystals always cubic?
The ionic bonds will form a lattice network
What is the arrangment of ions in crystals?
They are in a repeating, geometric pattern.A crystal's ions are arranged in an orderly, repeating, geometric pattern. Here's a link:http://www.scienceclarified.com/Co-Di/Crystal.htmlthey are happyin a orderly 3-D arrangement
