TIF The angular momentum quantum number is L. 22 TIF 23. ТЕ The atomic number for hydrogen like species affects both the kinetic and potential energy terms of the Hamiltonian. The total energy of hydrogen-like species is positive Each orbital has a unique wavefunction. For hydrogen-like species, the group of wavefunctions having the same energy comprise a shell 24. TIF 25. TIF 26. T/F Wavefunctions of a subshell have the same value but different I values. 27. T/F All electrons have spin of Y. 28. T/F 29. T/F Changing only the spin of an electron in the hydrogen atom will not change the energy Perturbation theory and variational theory are capable of high accuracy, Rotations in linear molecules are only observable along 2 orthogonal directions 30. T/F I hope our journey through quantum concepts this semester has helped to better explain the foundations of modern chemistry. I have enjoyed showing you the key findings of a remarkable human accomplishment. May you endeavor to learn all that you can Have a great summer! Dr. Turner
