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. You perform a nuclear physics experiment in which you bombard 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,...

The nucleus can become unstable when it contains more protons than neutrons because: 1. exchange forces compete with Coulombic forces 2. exchange forces cause neutrons to repel each other 3. exchange forces cause protons to repel each other 4. exchange forces have a shorter range than coulombic forces

Consider a simplified model of a triply ionized beryllium-9 atom (Be^1+): four protons plus five neutrons in the atom's nucleus, "orbited" by just one electron at a constant distance of 4.50 times 10^-12 m. You can solve (a) & (b) in either order. Label your work clearly: a. What is the strength (magnitude) of the attractive electric force between the nucleus and the electron? Show your work. b. What is the magnitude of the electric field at the electron's location?...
The size of the nucleus is about 10-14 m in diameter. If you wanted to add another proton to a Uranium nucleus (92 protons and 146 neutrons), how strong is the repulsive force at the "edge" of the nucleus?

The energy states of atoms containing more than one electron arise from nucleus-electron and electron- electron interactions. Which of the following statements correctly describes these effects? O Larger nuclear charge lowers energy; more electrons in an orbital lowers energy. O Larger nuclear charge lowers energy; more electrons in an orbital increases energy. O Smaller nuclear charge lowers energy; more electrons in an orbital lowers energy, O Smaller nuclear charge lowers energy; more electrons in an orbital increases energy. O None...
