    Number of atoms in FCC gold cube with only the radius given

    number of atoms in FCC gold cube with only the radius given! 1)it is given that the radius of a gold atom sphere is 144.2 pm, gold is packed in an FCC manner Give the ratio Ns/Nv as a function of L (gold cube side) and a parameter of FCC latice, knowing that Ns is the number of surface...

    Number of atoms in FCC gold cube

    what i am thinking is: in a unit cell we have 1/8 x 8 corner atoms = 1 atom and in the center of each phase we have 1/2 x 6 = 3 then the total number of atoms will be 4 atoms per unit = 4 volume of the cube is L^3 and volume of the unit is a^3 so if we want to know how many units are there in...
