Consider an electron in a 2s orbital of hydrogen (Z=1). Calculate the probability that the electron will be found anywhere in a shell formed by a region between a sphere of radius r and radius 1.0pm greater than the r value. Do this calculation in Excel for r from 1 to 600 pm in increments of 1pm. (You will be calculating the probability for successive shells at greater and greater distances from the nucleus.) Plot the resulting curve with probability...

Answer d
a. (4 points) Write the Hamiltonian for the neutral Li atom, explicitly including each kinetic and potential energy term. b. (4 points) For a one-electron atom, the 2s and 2p orbitals are degenerate. Why does one electron in Li occupy the 2s orbital instead of 2p? How does that relate to the expectation values for the radii of 2s and 2p you computed earlier on this homework? c. (4 points) Li has an ionization energy of 5.39 eV....
