You are on the Starship Enterprise visitin an uninhabited planet. While investigating the surface of the planet, you come across a "nugget" of some type. You take it aboard the Enterprise to determine some of its physical properties. You find that it has a melting point of 1000.0 C and is relatively heavy, density 11.655 g/mL and that the radius of the atom is found to be 144.8 pm. Into what type of unit cell (i.e., simple cubic fave-centered cubic, or body-centered cubic) does this material cystallize? Be sure to fully support your answer. The apparent atomic mass is 120.5 amu. Remember that 1 amu = 1.660538783 x 10^24 g.
