The number of atoms present in a fcc unit cell is

In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. Assertion: The total number of atoms present in a simple cubic unit cell is one. Reason: Simple cubic unit cell has atoms in its corners each of which is shared between eight adjacent unit cells.

Number of atoms present per unit cell in NaCl

The number of atoms present in a hexagonal close-packed unit cell is:

Fill ups The number of atoms for primitive unit cell is…………….for body centred cubic unit cell is…………..and for face centred cubic unit cell is………….. .

An element (density 7.2 gcm^-3) crystallizes in a body centred cubic structure having its unit cell edge length 2.88oversetcircA . Calculate the number of atoms present in 156 g of the element.

How many number of atoms are present in face centered cubic unit cell?

packing fraction of a unit cell is drfined as the fraction of the total volume of the unit cell occupied by the atom(s). P.E=("Volume of the atoms(s) present in a unit cell")/("Volume of unit cell")=(Zxx(4)/(3)pir^(3))/(a^(3)) and % of empty space = 100- P.F.xx100 where Z= effective number of atoms in s cube . r= radius of a an atoms a = edge length of the cube % of empty space in body centered cubic cell unit is nearly :
