Polonium (Po) is the only material which forms a simple cubic crystal (i.e., it is not FCC or BCC) structure with atoms at the corner positions. It is a metal (but it is radioactive so it has very few engineering applications!). Its atomic number is 84 and its atomic weight is 210. The unit cell edges a are 0.334 nm long.
a)  How many atoms per unit cell does it have?
b)  What is its density in gram/cm3?
c)  What is its Atomic Packing Factor, APF ?
