CONCEPTUAL PROBLEMS, Chapter 28 Phys 1404, Dr. Huang Fill in a T/F answer for each statement below: 1. [ ] Bohr's model was very successful to explain line spectra of helium. 2. [ ] Quantum mechanics is a probability theory, not a deterministic one. 3. [ ] From the quantum mechanics point of view, the future motion of an object can not be predicted precisely. 4. [ ] It is not possible to make a measurement of an object without somehow disturbing it. 5. [ ] Heisenberg uncertainty principle states that both the position and momentum of an object cannot be measured precisely at the same time. 6. [ ] Electron cloud can be considered as a probability distribution for electrons. 7. [ ] In quantum mechanics, the state of an electron in an atom is described by five quantum numbers. 8. [ ] For each orbital quantum number l, the magnetic quantum number can take 2l+1 possible values. 9. [ ] An electron can have three possible spin states: spin up, zero spin, and spin down. 10. [ ] Pauli exclusion principle states that no two electrons in an atom can occupy the same quantum state. 11. [ ] In ground state, the outer electron of a sodium atom occupies the M shell. 12. [ ] The maximum number of electrons that can be in a p subshell is 10.
