A proton in an atomic nucleus is bound to other protons and neutrons in the nucleus by the strong nuclear force when it is within approximately 3 fm of another particle. What is the approximate kinetic energy of a proton that is localized to such a region? What would be the corresponding energy of an electron localized to within such a region? Compare this to typical beta energies for beta decay. Is a release of electrons

What is natural radioactivity? Speak to the different types of radiation that an unstable nucleus may emit, and the different types of radiation involved. Why is it important to be able to write a balanced nuclear equation for radioactive decay? Go into some of the specifics of what is involved in writing an equation. What is a “half-life” and why is it important to know the half-life of a radioisotope? List a few applications of how scientists make use of...

What fraction of the α particles in Rutherford's gold foil experiment are scattered at large angles? Assume the gold foil is two layers thick, as shown in the figure, and that the approximate diameters of a gold atom and its nucleus are 1.5 Å and 1.5×10−4Å,

“Atomic fission” is when a nucleus gets hit by a neutron and splits in half, releasing a great deal of energy. It is the basic principle behind nuclear reactors and nuclear weapons. The “Fat Man” atomic bomb dropped on Nagasaki in 1945 had a plutonium core of 6.4 kg of the isotope Pu-239. (Note that “239” is the molar mass.) When the bomb exploded, it released an amount of energy equivalent to 21 kilotons of TNT. Although the bomb needed...

An atomic nucleus of mass m traveling with speed v collides elastically with a target particle of mass 2m (initially at rest) and is scattered at 90°. (a) At what angle does the target particle move after the collision? (b) What are the final speeds of the two particles? (c) What fraction of the initial kinetic energy is transferred to the target particle?

1. A one-electron atom has atomic number ?, mass number ? and a spherical nucleus of radius ? . Assume electric charge +?? is uniformly distributed throughout the volume of the nucleus. Ignoring spin, use first order non-degenerate perturbation theory and the hydrogenic wave functions adapted to the one-electron atom to determine the dependence of the ground state energy of the atom on ?

An atomic nucleus initially moving at 420m/s emits an alpha particle in the direction of its velocity, and the new nucleus slows to 346m/s. If the alpha particle has a mass of 2u and the original nucleus has a mass of 222u, what speed does the alpha particle have when it is emitted? I need a final correct answer in order to give full rating.
