A thin straight tube of length 1.0cm is completely filled, end to end, with identical spherical 79197Au nuclei that are just touching each other.
(a) Calculate the diameter of one 79197Au nucleus.
(b) Estimate the maximum number of such nuclei that can be accommodated in the tube.
(c) If the same tube were filled with 82207Pb nuclei instead, how many nuclei would fit? Compare the two results.
