Uranium-238 (U238) has three more neutrons than uranium-235 (U235). Compared to the speed of sound in a bar of U235, is the speed of sound in a bar of U238 higher, lower, or the same? There are
several factors that play a role.
(a) Chemically, the atoms of these two isotopes behave in essentially identical ways, since the number of protons (92) is identical and the clouds of 92 electrons are nearly identical. The interatomic
distance, and the effective "stiffness" of the interatomic bond, both depend on the chemical properties of the atoms. Therefore, which of the following statements are true?
O The effective stiffness of the interatomic "spring" is the same in the two isotopes, since this "spring" is a model for the interactions of the outer electrons, which are the same for different
isotopes of the same atom.
V The effective stiffness of the interatomic "spring" is greater for U238 because the mass is greater.
V The interatomic distance is the same for the two isotopes, because it…
The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six
protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. A graduate student
performs a nuclear physics experiment in which she bombards nitrogen-14 nuclei with very high speed carbon-12 nuclei
emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely, and a mix of
different particles are emitted, including electrons, protons, antiprotons (with electric charge
-e each), positrons (with
charge +e each), and various neutral particles (including neutrons and neutrinos).
For a particular collision, she detects the emitted products and find 17 protons, 4 antiprotons, 7 positrons, and 21 neutral
particles. How many electrons are also emitted?
