The nucleus of an atom can be modeled as several protons and neutrons closely packed together. Each particle has a mass of 1.67 ✕ 10−27 kg and radius on the order of 10−15 m.
(a) Use this model and the data provided to estimate the density of the nucleus of an atom.
kg/m3
(b) Compare your result with the density of a material such as iron

1. Let's consider a toy model of nuclear fission. Suppose an nucleus of Uranium-235 (92 protons, molar
weight of 235 g/mole) "splits" into two "daughter" nuclei of Palladium (46 protons each) – this is not
how it really happens, but it's a very simple model that actually gives fairly accurate results. The
radius of the original U-235 nucleus is about 7.4 x 10-15 m.
(a) If the Pd nuclei each have half the volume of the U nucleus, which is reasonable, and they are
"touching" right after the split, how far apart are their centers?
(b) Using conservation of energy, what will be the sum of the kinetic energies of the Pd nuclei
when they are far apart from each other?
(c) That's energy of one atom undergoing fission, so what, then, is the energy released by the
fission of 1 kg of U-235? Express this in Joules and also in kilotons of TNT, where 1 kt = 4.2x1012
J. (The Hiroshima bomb yielded about 15 kt)
(d) How many kwh (kilowatt-hours) of energy is this, (1 kwh = 3.6x10° J), and (if…
