For an electron in a 4f state, determine the principal quantum number and the orbital quantum number.   (a) the principal quantum number   (b) the orbital quantum number   (c) How many different magnetic quantum numbers are possible for an electron in that state?

Student A & B are studying the Zeeman effect. They observe that the energy of an electron in the p-level of an atom is changed in the presence of a magnetic field of magnitude 4.6 T. What is the difference between the largest and smallest possible energies?  (bohr magneton = μB = 9.27x10-24 J/T).

Three charged spheres are at the positions shown in the figure. (a) Find the net electrostatic force at sphere B. (b) Find the net electric field at (4,-3) 4 cm 4.5uC 8.2 μC B 3 cm 6.0uC

Chapter 39, Problem 044 A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of -1.51 eV makes a transition to a state with an excitation energy (the difference between the energy of the state and that of the ground state) of 10.200 eV. (a) What is the energy of the photon emitted as a result of the transition? What are the (b) higher quantum number and (c) lower quantum number of the transition producing this emission? Use -13.60 eV as the binding energy of an electron in the ground state. (a) Number Units (b) Number Units (c) Number Units
