Sodium metal (atomic weight 22.99 g/cm3) adopts a bodycentered cubic structure with a density of 0.97 g/cm3.
(a) Use this information and Avogadro's number (NA = 6.022 X 1023) to estimate the atomic radius of sodium.
(b) If it didn't react so vigorously, sodium could float on water. Use the answer from part (a) to estimate the density of Na if its structure were that of a cubic close-packed metal. Would it still float on water?
