A fcc unit cell of aluminium contains effectively how many atoms?

A cubic unit cell contains one atom at each of its corner and two atoms on each of its body diagonal. How many atoms does the unit cell contain?

Density of a unit cell is respresented as rho = (" Effective no. of atoms (s)" xx "Mass of a unit cell ")/("Volume of a unit cell ")=(Z.M)/(N_(A).a^(3)) where , Z =mass of effective no . of atoms(s) or ion (s). M= At . mass// formula N_(A) = Avogadro' s no . rArr 6.0323 xx 10^(23) a= edge length of unit cell An element crystallizes in a structure having fcc unit cell of an edge 200 pm . Calculate the density , if 100 g of this element contains 12xx10^(23) atoms :

Metallic sodium has a body-centred cubic unit cell. How many atoms are contained in one unit cell?

In F.C.C. the unit cell is shared equally by how many unit cells ?

In a face centred cubic (fcc) lattice, a unit cell is shared equally by how many unit cells?
