The electron can be either bound or unbound to the impurity atom, but the electron can also have one of 2 spins when bound. Since electrons move back and forth between the impurity atom and lattice, they are in diffusive equilibrium, and there is a chemical potential μ which is the same for all states. (a) Calculate the grand partition function for this system, and the probability that the electron is bound and unbound. Express your answers in terms of...

An electron in a multi-electron atom is partially shielded from the full charge of the nucleus by other electrons, and this leads to the idea of an effective nuclear charge Zeff. For example, for the Li atom where the true charge is Z=3, quantum calculations give an effective nuclear charge of 2.69 for the 1s electrons, and 1.28 for the 2s electron. Use the first and second ionization energies given below to estimate Zeff for the 2s and 1s electrons...

In the "Bohr model" of the Hydrogen atom, a single electron is said to have a circular orbit around the nucleus (in this case consisting of a single proton), analogously to how the Earth orbits the Sun. If the electron orbits at a distance of 1.5�10-10 m, What is the electric force felt by the electron? What speed must the electron have in order to maintain its orbit? ( in mi/hr and m/s)
