Iron occurs as BCC as well as FCC unit cell. If the effective radius of an atom of iron is 124 pm, compute the density of iron in both these structures.

A compound crystallizes in bcc structure. What is unit cell edge length if diameter of its atom is 120 pm?

Gold has a fcc lattice with edge length 407 pm. The diameter of the gold atom is

Iron occurs as bcc as well as fcc unit cell. If the effective radius of an atom of iron is 124 pm. Compute the density of iron in both these structures.

In a metal M having BCC arrangement edge length of the unit cell is 400 pm. The atomic radius of the metal is:

The portion of edge length not occupied by atoms for simple cubic, fcc and bcc are respectively (a is edge length)
